Primary vs Secondary Research – What’s the Difference?

In the search for knowledge and data to inform decisions, researchers and analysts rely on a blend of research sources. These sources are broadly categorized into primary and secondary research, each serving unique purposes and offering different insights into the subject matter at hand. But what exactly sets them apart?

Primary research is the process of gathering fresh data directly from its source. This approach offers real-time insights and specific information tailored to specific objectives set by stakeholders. Examples include surveys , interviews, and observational studies.

Secondary research , on the other hand, involves the analysis of existing data, most often collected and presented by others. This type of research is invaluable for understanding broader trends, providing context, or validating hypotheses. Common sources include scholarly articles, industry reports, and data compilations.

The crux of the difference lies in the origin of the information: primary research yields firsthand data which can be tailored to a specific business question, whilst secondary research synthesizes what's already out there. In essence, primary research listens directly to the voice of the subject, whereas secondary research hears it secondhand .

When to Use Primary and Secondary Research

Selecting the appropriate research method is pivotal and should be aligned with your research objectives. The choice between primary and secondary research is not merely procedural but strategic, influencing the depth and breadth of insights you can uncover.

Primary research shines when you need up-to-date, specific information directly relevant to your study. It's the go-to for fresh insights, understanding consumer behavior, or testing new theories. Its bespoke nature makes it indispensable for tailoring questions to get the exact answers you need.

A Complete Guide to Primary and Secondary Research in UX Design

To succeed in UX design, you must know what UX research methods to use for your projects.

This impacts how you:

• Understand and meet user needs
• Execute strategic and business-driven solutions
• Differentiate yourself from other designers
• Be more efficient in your resources
• Innovate within your market

Primary and secondary research methods are crucial to uncovering this. The former is when you gather firsthand data directly from sources, while the latter synthesizes existing data and translates them into insights and recommendations.

Let's dive deep into each type of research method and its role in UX research.

If you are still hungry to learn more, specifically how to apply it practically in the real world, you should check out Michael Wong's UX research course . He teaches you  the exact process and tactics he used that helped him build a UX agency that generated over $10M+ million in revenue.

What is p rimary research in UX design

Primary UX research gathers data directly from the users to understand their needs, behaviors, and preferences.

It's done through interviews, surveys, and observing users as they interact with a product.

Primary research in UX: When and why to use it

Primary research typically starts at the start of a UX project. This is so that the design process is grounded in a deep understanding of user needs and behaviors.

By collecting firsthand information early on, teams can tailor their designs to address real user problems.

Here are the reasons why primary research is important in UX design: ‍

1. It fast-tracks your industry understanding

Your knowledge about the industry may be limited at the start of the project. Primary research helps you get up to speed because you interact directly with real customers. As a result, this allows you to work more effectively.

Example: Imagine you're designing an app for coffee lovers. But you're not a coffee drinker yourself. Through user interviews, you learn how they prefer to order their favorite drink, what they love or hate about existing coffee apps, and their "wishlist" features by talking directly to them.

This crucial information will guide you on what to focus on in later stages when you do the actual designing. ‍

2. You'll gain clarity and fill knowledge gaps

There are always areas we know less about than we'd like. Primary research helps fill these gaps by observing user preferences and needs directly.

Example: Let's say you're working on a website for online learning. You might assume that users prefer video lessons over written content, but your survey results show that many users prefer written material because they can learn at their own pace.

With that in mind, you'll prioritize creating user-friendly design layouts for written lessons. ‍

3. You get to test and validate any uncertainties

When unsure about a feature, design direction, or user preference, primary research allows you to test these elements with real users.

This validation process helps you confidently move forward since you have data backing your decisions.

Example: You're designing a fitness app and can't decide between a gamified experience (with points and levels) or a more straightforward tracking system.

By prototyping both options and testing them with a group of users, you discover that the gamified experience concept resonates more.

Users are more motivated when they gain points and progress levels. As a result, you pivot to designing a better-gamified experience.

Types of primary research methods in UX design

Challenges of primary research in UX

Here are the obstacles that UX professionals may face with primary research:

• Time-consuming : Primary research requires significant planning, conducting, and analyzing. This is particularly relevant for methods that involve a lot of user interaction.
• Resource intensive : A considerable amount of resources is needed, including specialized tools or skills for data collection and analysis.
• Recruitment difficulties : Finding and recruiting suitable participants willing to put in the effort can be challenging and costly.
• Bias and validity : The risk of bias in collecting and interpreting data highlights the importance of carefully designing the research strategy. This is so that the findings are accurate and reliable. ‍

What is secondary research in UX design

Once primary research is conducted, secondary research analyzes and converts this data into insights. They may also find common themes and ideas and convert them into meaningful recommendations.

Using journey maps, personas, and affinity diagrams can help them better understand the problem.

Secondary research also involves reviewing existing research, published books, articles, studies, and online information. This includes competitor websites and online analytics to support design ideas and concepts. ‍

Secondary research in UX: Knowing when and why to use it

Secondary research is a flexible method in the design process. It fits in both before and after primary research.

At the project's start, looking at existing research and what's already known can help shape your design strategy. This groundwork helps you understand the design project in a broader context.

After completing your primary research, secondary research comes into play again. This time, it's about synthesizing your findings and forming insights or recommendations for your stakeholders.

Here's why it's important in your design projects:

1. It gives you a deeper understanding of your existing research

Secondary research gathers your primary research findings to identify common themes and patterns. This allows for a more informed approach and uncovers opportunities in your design process.

Example: When creating personas or proto-personas for a fitness app, you might find common desires for personalized workout plans and motivational features.

This data shapes personas like "Fitness-focused Fiona," a detailed profile that embodies a segment of your audience with her own set of demographics, fitness objectives, challenges, and likes. ‍

2. Learn more about competitors

Secondary research in UX is also about leveraging existing data in the user landscape and competitors.

This may include conducting a competitor or SWOT analysis so that your design decisions are not just based on isolated findings but are guided by a comprehensive overview. This highlights opportunities for differentiation and innovation.

Example: Suppose you're designing a budgeting app for a startup. You can check Crunchbase, an online database of startup information, to learn about your competitors' strengths and weaknesses.

If your competitor analysis reveals that all major budgeting apps lack personalized advice features, this shows an opportunity for yours to stand out by offering customized budgeting tips and financial guidance. ‍

Types of secondary research methods in UX

1. competitive analysis.

• What is it: Competitive analysis involves systematically comparing your product with its competitors in the market. It's a strategic tool that helps identify where your product stands about the competition and what unique value proposition it can offer.
• Best used for: Identifying gaps in the market that your product can fill, understanding user expectations by analyzing what works well in existing products, and pinpointing areas for improvement in your own product.
• Tools: Google Sheets to organize and visualize your findings; Crunchbase and SimilarWeb to look into competitor performance and market positioning; and UserVoice to get insights into what users say about your competitors.

2. Affinity mapping

• What is it: A collaborative sorting technique used to organize large sets of information into groups based on their natural relationships.
• Best used for: Grouping insights from user research, brainstorming sessions, or feedback to identify patterns, themes, and priorities. It helps make sense of qualitative data, such as user interview transcripts, survey responses, or usability test observations.
• Tools: Miro and FigJam for remote affinity mapping sessions.

3. Customer journey mapping

• What is it: The process of creating a visual representation of the customer's experience with a product or service over time and across different touchpoints.
• Best used for: Visualizing the user's path from initial engagement through various interactions to the final goal.
• Tools: FigJam and Google Sheets for collaborative journey mapping efforts.

4. Literature and academic review

• What is it: This involves examining existing scholarly articles, books, and other academic publications relevant to your design project. The goal is to deeply understand your project's theoretical foundations, past research findings, and emerging trends.
• Best used for: Establishing a solid theoretical framework for your design decisions. A literature review can uncover insights into user behavior and design principles that inform your design strategy.
• Tools: Academic databases like Google Scholar, JSTOR, and specific UX/UI research databases. Reference management tools like Zotero and Mendeley can help organize your sources and streamline the review process.

Challenges of secondary research in UX design

These are the challenges that UX professionals might encounter when carrying out secondary research:

• Outdated information : In a world where technology changes fast, the information you use must be current, or it might not be helpful.
• Challenges with pre-existing data : Using data you didn't collect yourself can be tricky because you have less control over its quality. Always review how it was gathered to avoid mistakes.
• Data isn't just yours : Since secondary data is available to everyone, you won't be the only one using it. This means your competitors can access similar findings or insights.
• Trustworthiness : Look into where your information comes from so that it's reliable. Watch out for any bias in the data as well. ‍

The mixed-method approach: How primary and secondary research work together

Primary research lays the groundwork, while secondary research weaves a cohesive story and connects the findings to create a concrete design strategy.

Here's how this mixed-method approach works in a sample UX project for a health tech app:

Phase 1: Groundwork and contextualization

• User interviews and surveys (Primary research) : The team started their project by interviewing patients and healthcare providers. The objective was to uncover the main issues with current health apps and what features could enhance patient care.
• Industry and academic literature review (Secondary research) : The team also reviewed existing literature on digital health interventions, industry reports on health app trends, and case studies on successful health apps. ‍

Phase 2: Analysis and strategy formulation

• Affinity mapping (Secondary research) : Insights from the interviews and surveys were organized using affinity mapping. It revealed key pain points like needing more personalized and interactive care plans.
• Competitive benchmarking (Secondary research) : The team also analyzed competitors’ apps through secondary research to identify common functionalities and gaps. They noticed a lack of personalized patient engagement and, therefore, positioned their app to fill this void in the market. ‍

Phase 3: Design and validation

• Prototyping (Secondary research) : With a good grasp of what users need and the opportunities in the market, the startup created prototypes. These prototypes include AI-powered personalized care plans, reminders for medications, and interactive tools to track health.
• Usability testing (Primary research) : The prototypes were tested with a sample of the target user group, including patients and healthcare providers. Feedback was mostly positive, especially for the personalized care plans. This shows that the app has the potential to help patients get more involved in their health. ‍

Phase 4: Refinement and market alignment

• Improving design through iterations: The team continuously refined the app's design based on feedback from ongoing usability testing.
• Ongoing market review (Secondary research) : The team watched for new studies, healthcare reports, and competitors' actions. This helped them make sure their app stayed ahead in digital health innovation. ‍

The choice of study type is an important aspect of the design of medical studies. The study design and consequent study type are major determinants of a study’s scientific quality and clinical value.

This article describes the structured classification of studies into two types, primary and secondary, as well as a further subclassification of studies of primary type. This is done on the basis of a selective literature search concerning study types in medical research, in addition to the authors’ own experience.

Three main areas of medical research can be distinguished by study type: basic (experimental), clinical, and epidemiological research. Furthermore, clinical and epidemiological studies can be further subclassified as either interventional or noninterventional.

Conclusions

The study type that can best answer the particular research question at hand must be determined not only on a purely scientific basis, but also in view of the available financial resources, staffing, and practical feasibility (organization, medical prerequisites, number of patients, etc.).

The quality, reliability and possibility of publishing a study are decisively influenced by the selection of a proper study design. The study type is a component of the study design (see the article "Study Design in Medical Research") and must be specified before the study starts. The study type is determined by the question to be answered and decides how useful a scientific study is and how well it can be interpreted. If the wrong study type has been selected, this cannot be rectified once the study has started.

After an earlier publication dealing with aspects of study design, the present article deals with study types in primary and secondary research. The article focuses on study types in primary research. A special article will be devoted to study types in secondary research, such as meta-analyses and reviews. This article covers the classification of individual study types. The conception, implementation, advantages, disadvantages and possibilities of using the different study types are illustrated by examples. The article is based on a selective literature research on study types in medical research, as well as the authors’ own experience.

Classification of study types

In principle, medical research is classified into primary and secondary research. While secondary research summarizes available studies in the form of reviews and meta-analyses, the actual studies are performed in primary research. Three main areas are distinguished: basic medical research, clinical research, and epidemiological research. In individual cases, it may be difficult to classify individual studies to one of these three main categories or to the subcategories. In the interests of clarity and to avoid excessive length, the authors will dispense with discussing special areas of research, such as health services research, quality assurance, or clinical epidemiology. Figure 1 gives an overview of the different study types in medical research.

Classification of different study types

*1 , sometimes known as experimental research; *2 , analogous term: interventional; *3 , analogous term: noninterventional or nonexperimental

This scheme is intended to classify the study types as clearly as possible. In the interests of clarity, we have excluded clinical epidemiology — a subject which borders on both clinical and epidemiological research ( 3 ). The study types in this area can be found under clinical research and epidemiology.

Basic research

Basic medical research (otherwise known as experimental research) includes animal experiments, cell studies, biochemical, genetic and physiological investigations, and studies on the properties of drugs and materials. In almost all experiments, at least one independent variable is varied and the effects on the dependent variable are investigated. The procedure and the experimental design can be precisely specified and implemented ( 1 ). For example, the population, number of groups, case numbers, treatments and dosages can be exactly specified. It is also important that confounding factors should be specifically controlled or reduced. In experiments, specific hypotheses are investigated and causal statements are made. High internal validity (= unambiguity) is achieved by setting up standardized experimental conditions, with low variability in the units of observation (for example, cells, animals or materials). External validity is a more difficult issue. Laboratory conditions cannot always be directly transferred to normal clinical practice and processes in isolated cells or in animals are not equivalent to those in man (= generalizability) ( 2 ).

Basic research also includes the development and improvement of analytical procedures—such as analytical determination of enzymes, markers or genes—, imaging procedures—such as computed tomography or magnetic resonance imaging—, and gene sequencing—such as the link between eye color and specific gene sequences. The development of biometric procedures—such as statistical test procedures, modeling and statistical evaluation strategies—also belongs here.

Clinical studies

Clinical studies include both interventional (or experimental) studies and noninterventional (or observational) studies. A clinical drug study is an interventional clinical study, defined according to §4 Paragraph 23 of the Medicines Act [Arzneimittelgesetz; AMG] as "any study performed on man with the purpose of studying or demonstrating the clinical or pharmacological effects of drugs, to establish side effects, or to investigate absorption, distribution, metabolism or elimination, with the aim of providing clear evidence of the efficacy or safety of the drug."

Interventional studies also include studies on medical devices and studies in which surgical, physical or psychotherapeutic procedures are examined. In contrast to clinical studies, §4 Paragraph 23 of the AMG describes noninterventional studies as follows: "A noninterventional study is a study in the context of which knowledge from the treatment of persons with drugs in accordance with the instructions for use specified in their registration is analyzed using epidemiological methods. The diagnosis, treatment and monitoring are not performed according to a previously specified study protocol, but exclusively according to medical practice."

The aim of an interventional clinical study is to compare treatment procedures within a patient population, which should exhibit as few as possible internal differences, apart from the treatment ( 4 , e1 ). This is to be achieved by appropriate measures, particularly by random allocation of the patients to the groups, thus avoiding bias in the result. Possible therapies include a drug, an operation, the therapeutic use of a medical device such as a stent, or physiotherapy, acupuncture, psychosocial intervention, rehabilitation measures, training or diet. Vaccine studies also count as interventional studies in Germany and are performed as clinical studies according to the AMG.

Interventional clinical studies are subject to a variety of legal and ethical requirements, including the Medicines Act and the Law on Medical Devices. Studies with medical devices must be registered by the responsible authorities, who must also approve studies with drugs. Drug studies also require a favorable ruling from the responsible ethics committee. A study must be performed in accordance with the binding rules of Good Clinical Practice (GCP) ( 5 , e2 – e4 ). For clinical studies on persons capable of giving consent, it is absolutely essential that the patient should sign a declaration of consent (informed consent) ( e2 ). A control group is included in most clinical studies. This group receives another treatment regimen and/or placebo—a therapy without substantial efficacy. The selection of the control group must not only be ethically defensible, but also be suitable for answering the most important questions in the study ( e5 ).

Clinical studies should ideally include randomization, in which the patients are allocated by chance to the therapy arms. This procedure is performed with random numbers or computer algorithms ( 6 – 8 ). Randomization ensures that the patients will be allocated to the different groups in a balanced manner and that possible confounding factors—such as risk factors, comorbidities and genetic variabilities—will be distributed by chance between the groups (structural equivalence) ( 9 , 10 ). Randomization is intended to maximize homogeneity between the groups and prevent, for example, a specific therapy being reserved for patients with a particularly favorable prognosis (such as young patients in good physical condition) ( 11 ).

Blinding is another suitable method to avoid bias. A distinction is made between single and double blinding. With single blinding, the patient is unaware which treatment he is receiving, while, with double blinding, neither the patient nor the investigator knows which treatment is planned. Blinding the patient and investigator excludes possible subjective (even subconscious) influences on the evaluation of a specific therapy (e.g. drug administration versus placebo). Thus, double blinding ensures that the patient or therapy groups are both handled and observed in the same manner. The highest possible degree of blinding should always be selected. The study statistician should also remain blinded until the details of the evaluation have finally been specified.

A well designed clinical study must also include case number planning. This ensures that the assumed therapeutic effect can be recognized as such, with a previously specified statistical probability (statistical power) ( 4 , 6 , 12 ).

It is important for the performance of a clinical trial that it should be carefully planned and that the exact clinical details and methods should be specified in the study protocol ( 13 ). It is, however, also important that the implementation of the study according to the protocol, as well as data collection, must be monitored. For a first class study, data quality must be ensured by double data entry, programming plausibility tests, and evaluation by a biometrician. International recommendations for the reporting of randomized clinical studies can be found in the CONSORT statement (Consolidated Standards of Reporting Trials, www.consort-statement.org ) ( 14 ). Many journals make this an essential condition for publication.

For all the methodological reasons mentioned above and for ethical reasons, the randomized controlled and blinded clinical trial with case number planning is accepted as the gold standard for testing the efficacy and safety of therapies or drugs ( 4 , e1 , 15 ).

In contrast, noninterventional clinical studies (NIS) are patient-related observational studies, in which patients are given an individually specified therapy. The responsible physician specifies the therapy on the basis of the medical diagnosis and the patient’s wishes. NIS include noninterventional therapeutic studies, prognostic studies, observational drug studies, secondary data analyses, case series and single case analyses ( 13 , 16 ). Similarly to clinical studies, noninterventional therapy studies include comparison between therapies; however, the treatment is exclusively according to the physician’s discretion. The evaluation is often retrospective. Prognostic studies examine the influence of prognostic factors (such as tumor stage, functional state, or body mass index) on the further course of a disease. Diagnostic studies are another class of observational studies, in which either the quality of a diagnostic method is compared to an established method (ideally a gold standard), or an investigator is compared with one or several other investigators (inter-rater comparison) or with himself at different time points (intra-rater comparison) ( e1 ). If an event is very rare (such as a rare disease or an individual course of treatment), a single-case study, or a case series, are possibilities. A case series is a study on a larger patient group with a specific disease. For example, after the discovery of the AIDS virus, the Center for Disease Control (CDC) in the USA collected a case series of 1000 patients, in order to study frequent complications of this infection. The lack of a control group is a disadvantage of case series. For this reason, case series are primarily used for descriptive purposes ( 3 ).

Epidemiological studies

The main point of interest in epidemiological studies is to investigate the distribution and historical changes in the frequency of diseases and the causes for these. Analogously to clinical studies, a distinction is made between experimental and observational epidemiological studies ( 16 , 17 ).

Interventional studies are experimental in character and are further subdivided into field studies (sample from an area, such as a large region or a country) and group studies (sample from a specific group, such as a specific social or ethnic group). One example was the investigation of the iodine supplementation of cooking salt to prevent cretinism in a region with iodine deficiency. On the other hand, many interventions are unsuitable for randomized intervention studies, for ethical, social or political reasons, as the exposure may be harmful to the subjects ( 17 ).

Observational epidemiological studies can be further subdivided into cohort studies (follow-up studies), case control studies, cross-sectional studies (prevalence studies), and ecological studies (correlation studies or studies with aggregated data).

In contrast, studies with only descriptive evaluation are restricted to a simple depiction of the frequency (incidence and prevalence) and distribution of a disease within a population. The objective of the description may also be the regular recording of information (monitoring, surveillance). Registry data are also suited for the description of prevalence and incidence; for example, they are used for national health reports in Germany.

In the simplest case, cohort studies involve the observation of two healthy groups of subjects over time. One group is exposed to a specific substance (for example, workers in a chemical factory) and the other is not exposed. It is recorded prospectively (into the future) how often a specific disease (such as lung cancer) occurs in the two groups ( figure 2a ). The incidence for the occurrence of the disease can be determined for both groups. Moreover, the relative risk (quotient of the incidence rates) is a very important statistical parameter which can be calculated in cohort studies. For rare types of exposure, the general population can be used as controls ( e6 ). All evaluations naturally consider the age and gender distributions in the corresponding cohorts. The objective of cohort studies is to record detailed information on the exposure and on confounding factors, such as the duration of employment, the maximum and the cumulated exposure. One well known cohort study is the British Doctors Study, which prospectively examined the effect of smoking on mortality among British doctors over a period of decades ( e7 ). Cohort studies are well suited for detecting causal connections between exposure and the development of disease. On the other hand, cohort studies often demand a great deal of time, organization, and money. So-called historical cohort studies represent a special case. In this case, all data on exposure and effect (illness) are already available at the start of the study and are analyzed retrospectively. For example, studies of this sort are used to investigate occupational forms of cancer. They are usually cheaper ( 16 ).

Graphical depiction of a prospective cohort study (simplest case [2a]) and a retrospective case control study (2b)

In case control studies, cases are compared with controls. Cases are persons who fall ill from the disease in question. Controls are persons who are not ill, but are otherwise comparable to the cases. A retrospective analysis is performed to establish to what extent persons in the case and control groups were exposed ( figure 2b ). Possible exposure factors include smoking, nutrition and pollutant load. Care should be taken that the intensity and duration of the exposure is analyzed as carefully and in as detailed a manner as possible. If it is observed that ill people are more often exposed than healthy people, it may be concluded that there is a link between the illness and the risk factor. In case control studies, the most important statistical parameter is the odds ratio. Case control studies usually require less time and fewer resources than cohort studies ( 16 ). The disadvantage of case control studies is that the incidence rate (rate of new cases) cannot be calculated. There is also a great risk of bias from the selection of the study population ("selection bias") and from faulty recall ("recall bias") (see too the article "Avoiding Bias in Observational Studies"). Table 1 presents an overview of possible types of epidemiological study ( e8 ). Table 2 summarizes the advantages and disadvantages of observational studies ( 16 ).

1 = slight; 2 = moderate; 3 = high; N/A, not applicable.

*Individual cases may deviate from this pattern.

Selecting the correct study type is an important aspect of study design (see "Study Design in Medical Research" in volume 11/2009). However, the scientific questions can only be correctly answered if the study is planned and performed at a qualitatively high level ( e9 ). It is very important to consider or even eliminate possible interfering factors (or confounders), as otherwise the result cannot be adequately interpreted. Confounders are characteristics which influence the target parameters. Although this influence is not of primary interest, it can interfere with the connection between the target parameter and the factors that are of interest. The influence of confounders can be minimized or eliminated by standardizing the procedure, stratification ( 18 ), or adjustment ( 19 ).

The decision as to which study type is suitable to answer a specific primary research question must be based not only on scientific considerations, but also on issues related to resources (personnel and finances), hospital capacity, and practicability. Many epidemiological studies can only be implemented if there is access to registry data. The demands for planning, implementation, and statistical evaluation for observational studies should be just as high for observational studies as for experimental studies. There are particularly strict requirements, with legally based regulations (such as the Medicines Act and Good Clinical Practice), for the planning, implementation, and evaluation of clinical studies. A study protocol must be prepared for both interventional and noninterventional studies ( 6 , 13 ). The study protocol must contain information on the conditions, question to be answered (objective), the methods of measurement, the implementation, organization, study population, data management, case number planning, the biometric evaluation, and the clinical relevance of the question to be answered ( 13 ).

Important and justified ethical considerations may restrict studies with optimal scientific and statistical features. A randomized intervention study under strictly controlled conditions of the effect of exposure to harmful factors (such as smoking, radiation, or a fatty diet) is not possible and not permissible for ethical reasons. Observational studies are a possible alternative to interventional studies, even though observational studies are less reliable and less easy to control ( 17 ).

A medical study should always be published in a peer reviewed journal. Depending on the study type, there are recommendations and checklists for presenting the results. For example, these may include a description of the population, the procedure for missing values and confounders, and information on statistical parameters. Recommendations and guidelines are available for clinical studies ( 14 , 20 , e10 , e11 ), for diagnostic studies ( 21 , 22 , e12 ), and for epidemiological studies ( 23 , e13 ). Since 2004, the WHO has demanded that studies should be registered in a public registry, such as www.controlled-trials.com or www.clinicaltrials.gov . This demand is supported by the International Committee of Medical Journal Editors (ICMJE) ( 24 ), which specifies that the registration of the study before inclusion of the first subject is an essential condition for the publication of the study results ( e14 ).

When specifying the study type and study design for medical studies, it is essential to collaborate with an experienced biometrician. The quality and reliability of the study can be decisively improved if all important details are planned together ( 12 , 25 ).

Peer-Reviewed Literature: Peer-Reviewed Research: Primary vs. Secondary

• Peer-Reviewed Research: Primary vs. Secondary
• Types of Peer Review
• Identifying Peer-Reviewed Research

Peer Reviewed Research

Published literature can be either peer-reviewed or non-peer-reviewed. Official research reports are almost always peer reviewed while a journal's other content is usually not. In the health sciences, official research can be primary, secondary, or even tertiary. It can be an original experiment or investigation (primary), an analysis or evaluation of primary research (secondary), or findings that compile secondary research (tertiary). If you are doing research yourself, then primary or secondary sources can reveal more in-depth information.

Primary Research

Primary research is information presented in its original form without interpretation by other researchers. While it may acknowledge previous studies or sources, it always presents original thinking, reports on discoveries, or new information about a topic.

Health sciences research that is primary includes both experimental trials and observational studies where subjects may be tested for outcomes or investigated to gain relevant insight.  Randomized Controlled Trials are the most prominent experimental design because randomized subjects offer the most compelling evidence for the effectiveness of an intervention. See the below graphic and below powerpoint for further information on primary research studies.

• Research Design

Secondary Research

Secondary research is an account of original events or facts. It is secondary to and retrospective of the actual findings from an experiment or trial. These studies may be appraised summaries, reviews, or interpretations of primary sources and often exclude the original researcher(s). In the health sciences, meta-analysis and systematic reviews are the most frequent types of secondary research. 

• A meta-analysis is a quantitative method of combining the results of primary research. In analyzing the relevant data and statistical findings from experimental trials or observational studies, it can more accurately calculate effective resolutions regarding certain health topics.
• A systematic review is a summary of research that addresses a focused clinical question in a systematic, reproducible manner. In order to provide the single best estimate of effect in clinical decision making, primary research studies are pooled together and then filtered through an inclusion/exclusion process. The relevant data and findings are then compiled and synthesized to arrive at a more accurate conclusion about a specific health topic. Only peer-reviewed publications are used and analyzed in a methodology which may or may not include a meta-analysis.

• Knowledge Check Activity

Different databases may contain different types of sources. When you are conducting research you need to consider what types are most likely to contain the type of information you need to answer your research question. Depending on the database you might find books, magazine articles, trade publication articles, scholarly journal articles, documents, newspapers, videos, audio clips, images, et cetera. For the purposes of your Education Literature Review we will focus on sources that are primary research studies. Before you can do that, you need to know the difference between primary research and secondary research, how to identify which one you are looking at when you evaluate a source that you find and why the emphasis gets placed on using primary research studies.

Primary Research: This is research that is done by the author of the source you are using where that author conducted some method of research to gather new data that s/he then reports, analyzes and interprets in that source. Primary = original, first-hand; the author of the source generated the research data they are using.

Secondary Research: This is when an author of the source you are using gathers existing data, usually produced by someone else, and they then report, analyze or interpret that other person's data. Secondary = second-hand; the author of the source did not generate the research data s/he is using.

Tips when first evaluating a source: Once you find a research-based source, read the abstract and/or methodologies section and ask yourself who conducted the actual research process to gather the data?

• If the author(s) indicate they gathered the data first-hand by surveying a specific population, creating and running an experiment, conducting a focus group, observing a specific population/task, et cetera, they are doing primary research.
• If the author(s) indicate that they used only data gathered from other people's research studies by reviewing the literature or research, they are doing secondary research. 

Common sources where primary research in the field of Education is published are:

• Scholarly/academic journals - these are journals that are published by academic publishers (colleges, universities, et cetera) and professional organizations.
• Conference Proceedings
• Dissertations
• District, State or National Reports

Any of the above sources may also be peer-reviewed, meaning that the content is reviewed by other professionals in the field before it is published. Peer-reviewed, scholarly journals are considered to be high quality and often are a requirement in your research assignments because they are produced by experts and professionals in the field and all primary research articles are put through a peer-reviewed vetting process that is detailed by the journal publisher. It is also where professionals in the field in turn tend to publish their research for those same reasons. It is important to keep a couple of things in mind:

• Not all scholarly/academic journals are peer-reviewed.
• Not every article in a peer-reviewed journal is a primary research article or even a secondary research article. These journals often contain book/product reviews, opinion pieces, advice for practitioners, literature reviews, et cetera.
• Books take longer to publish and when you need current research/data this is a consideration. It can also be hard to determine what, if any type of peer-review process a book has gone through.
• Dissertations are by their very nature peer-reviewed, especially at the doctoral level, but can be hard to access as they are often only available at the university where the dissertation was written.
• In Education, district/state/national reports may be peer-reviewed, but like with books this can be hard to determine.

Research Databases are a great tool for finding and accessing primary research articles published in scholarly/academic, peer-reviewed journals. In the field of Education our library provides access to ERIC, Education Source, Proquest Education Database and Academic Search Ultimate. Each of these databases have search functions to help you narrow your results list down to scholarly/academic, peer-reviewed journals.

Depending on your topic and research question you may need to explore research databases in other disciplines as well. Here are two examples:

• Does gender impact bullying in middle school? In edition to Education databases I might want to also look at psychology (from the aspect of gender and behavior) and criminal justice databases (from the perspective that bullying can be a crime and looking at gender/age based statistics)
• What impact does arts therapy have on children with behavioral issues in the classroom? In edition to Education databases I might want to also look at psychology and medical databases (from the aspect of children with behavioral issues and arts therapy methods)

Research Methods: How and When to Use Primary and Secondary Research

• Survey Tips

What is Primary Research?

Primary research is research conducted by you or your team that examines and collects information directly from the context of the design problem. 

Simply put, primary research is research that is your own original work.

For example, if a researcher is interested in learning about the dietary habits of people in a particular region, he or she could administer a survey to residents of that region inquiring about what types of food they typically eat. 

Here, the researcher would be performing primary research.

What is Secondary Research?

Contrary to primary research, secondary research is research that was originally conducted by someone else.

Using our example from above, if after doing some investigation the researcher learns that a similar study has already been performed, he or she could utilize the results and findings from that study to assist him with his overall goal. 

Here the researcher would be performing secondary research.

Related: Why You Should Consider Secondary Data Analysis for Your Next Study 

Secondary research can be performed by leveraging the following sources:

• Academic peer-reviewed journals

• Magazines

• Books

• Market research reports

• Any other form of publicly available and accessible information


When to Use Secondary Research

Use secondary research as a starting point for your research process. .

Imagine that you’ve been tasked with developing an exercise program for elderly people. 

The goal of the program is to outline and schedule exercises and workouts in order to promote healthy lifestyles amongst senior citizens. 

But there’s a catch — You don’t have any experience in exercise science or developing this kind of program. 

The best place to start in order to kick off the project would be to leverage existing research.

You could review publicly available materials on exercise regimens optimized for the age of your target audience. This could involve reading published research reports, books, or articles.

Your findings from this secondary research could then help you define your own approach for how you plan to create the fitness plan for senior citizens. Additionally, starting with secondary research gives you an understanding of what's already been done, and it alerts you of where there may be gaps. 

Secondary research can help you understand what you don’t know.

Continuing on with our example above, you may realize that after researching existing materials on senior citizens and exercising that you know very little about what will motivate elderly people to exercise. 

If you find yourself in a similar situation, continue to identify resources to educate yourself on the matter at hand. 

In this case, secondary research has already saved you some time. If you had opted to not perform secondary research, and instead had made an attempt to build the exercise program from scratch using gut instinct, you would have spent a considerable amount of time banging your head against a theoretical wall to no avail.

If after digging into the available secondary sources, you realize that you still don’t have the precise knowledge needed to develop an effective program, you might then decide that primary research is the only viable way for you to move forward. 

Using Primary Research and Secondary Research Together

Once you have a deep understanding of the problem at hand thanks to your secondary research, you can then plan your primary research efforts accordingly, so that you can fill in any gaps and obtain any information that was previously missing.

Both methods are most effective when they work together.

Surveys Are Great Tools for Performing Primary Research 

Surveys are one of the most commonly used ways in which original data not found through secondary research is collected. 

This is because surveys are context-specific, meaning that the data collected from the survey comes directly from your exact target audience. Plus, there are essentially limitless ways to customize and tailor your survey to resonate with your target audience, which allows you to collect only the most pertinent data for your project.

• Key Differences

Know the Differences & Comparisons

Difference Between Primary and Secondary Research

On the contrary, Secondary research is a research method which involves the use of data, already collected through primary research. The main difference between primary and secondary research lies in the fact that whether the research is conducted previously or not.

Content: Primary Research Vs Secondary Research

Comparison chart.

Definition of Primary Research

A type of research, wherein the research aims at acquiring new and original data by primary sources, is known as Primary Data. As the term ‘primary’ implies ‘first and foremost’ and when it is linked with research, it means an in-depth exploration of facts by the researcher himself and that too with the one to one communication with the people, who know about the subject.

It is a bit difficult to conduct primary research because it requires a lot of time, money, resources and some prior information about the subject. With a view to getting needed information, the researcher has to start from scratch. The research can be performed through interviews, questionnaires, observations, etc.

Definition of Secondary Research

The research which involves analysis, interpretation and summarization of primary research, is called secondary research. In finer terms, the research in which data is obtained from readily available sources is secondary. As the data available is already analysed and interpreted, the researcher only needs to figure out the data of his choice, i.e. the relevant information for the project.

In this type of research, the researcher uses information gathered by government agencies, associations, labour unions media sources and so on. The data assembled is primarily published in newsletters, magazines, pamphlets, newspapers, journals, reports, encyclopaedias etc.

Key Differences Between Primary and Secondary Research

You can find out the difference between primary and secondary research, in the following points in detail:

• Research conducted to gather first-hand information, for the current problem is called Primary Research. Secondary Research is one that involves the use of information obtained originally by primary research.
• Primary Research is based on raw data, whereas secondary research is based on analysed and interpreted information.
• The primary research, the data is collected by the researcher himself or by the person hired by him. As against this, the secondary research, the data collection is performed by someone else.
• The primary research process is very involved which deeply explores the topic. Conversely, the secondary research process is fast and easy, which aims at gaining broad understanding about the subject.
• In primary research, as the researcher conducts the research, the data collected is always specific to the needs of the researcher. As opposed to secondary research, wherein the data lacks particularity, i.e. it may or may not be as per the requirements of the researcher.
• Primary research is an expensive process; wherein high cost is involved in the exploration of data and facts from various sources. Unlike Secondary research, is an economical process wherein the low cost is involved in acquiring pertinent information because the data is already collected by someone else.
• Primary research consumes a lot of time as the research is done from scratch. However, in the case of secondary research, the collection of data is already done, the research takes comparatively less time.

Both primary and secondary research have their advantages and disadvantages. While primary data is need-specific and quality is also up to the mark, but it is expensive and consumes more time. Secondary research, on the other hand, is cheap, and the data collection is easy, but it is also possible that the data may be outdated and does not suit your requirements. So, before choosing any of these two, first examine your requirements, sources, costs, etc. to choose the best research type for your project.

Chapter 9 – Secondary and Primary Research

Learning Objectives

• Differentiate between secondary and primary market research
• Distinguish between traditional marketing and entrepreneurial marketing
• Describe the seven elements of the marketing mix

Market research is essential during the planning phases of any start-up; otherwise, you’re shooting in the dark. On a basic level,  market research  is the collection and analysis of data related to a business’s target market. Market research can entail everything from information on competitors’ products to the interpretation of demographic data related to potential customers.

The main purpose of market research is to gain an understanding of customer needs and wants in an effort to reveal potential business opportunities. When you have a clear picture of what your target market is and what it wants, you can more effectively design your marketing mix to engage that  demographic .

Imagine that you are creating a cosmetic line that is organic, contains vitamins and minerals, and is easy to apply. Your target market is women who are interested in high-quality beauty products that are not harmful to themselves or the environment. But after conducting extensive market research, you learn that women aged eighteen to forty-five years tend to be interested in the benefits your product line provides, but that women over fifty years of age are not. In light of these findings, you can either adjust your line’s benefits to serve the market you initially wanted to serve (all women), or you can cater to the needs of a smaller audience (eighteen to forty-five-year-old women).

A good exercise for better understanding your  target market  is to detail the everyday life of your ideal customer. You can do this by describing in detail a set of possible customers who would buy your product. Details could include demographic information such as gender, age, income, education, ethnicity, social class, location, and life cycle. Other information that would be helpful would include psychographics (activities, hobbies, interests, and lifestyles) as well as behavior (how often they use a product or how they feel about it). The better you know your ideal customer, the better you can focus on capturing their attention by matching their preferences with your offerings.

Market research also helps you understand who your competitors are and how they serve the target market you want to engage. The more you know about your competition, the easier it will be to determine and differentiate your offerings. Let’s dive into how marketers gather all of these data and the value the data provide to entrepreneurs.

Secondary Market Research

Secondary research is research that uses existing data that has been collected by another entity. Oftentimes, these data are collected by governmental agencies to answer a wide range of questions or issues that are common to many organizations and people. Secondary research often answers more general questions that an entrepreneur may have, such as population information, average purchases, or trends. If there is a specific question that cannot be answered, such as how many people would be interested in a new product with certain attributes, then primary research will have to answer that. While some of this kind of research must be purchased, much of it is free to the public and a good option for entrepreneurs with limited financial resources.

Some useful resources are trade organizations that provide information about specific industries, as well as newspapers, magazines, journals, chambers of commerce, and other organizations that collect local, state, national, and international data. Resources such as these can provide information about everything from population size to community demographics and spending habits. Table 9.1 below lists several free databases that are rich sources of information.

Primary Market Research

Primary research entails collecting new data for the purpose of answering a specific question or set of questions. While conducting your own research can be resource intense, it is also the best way to get answers specific to your business and products, especially if you want to penetrate niche markets that have not been studied. It also allows you to get specific. By asking the right questions, you can determine people’s feelings and attitudes toward your brand, whether they like your product design, whether they value its proposed benefits, and whether they think it is priced fairly. Figure 9.1 shows the steps common in conducting primary market research.

• You should start by defining the goal of your research project. What are you trying to find out? The more time you take to clarify your research questions, the more likely you will be to achieve your research goals.

The next step is to determine which research techniques will most effectively help you answer your questions. Considering what you want to learn and determining what your budget is will help you decide if qualitative or quantitative research best suits your needs. Well-designed research projects often use some combination of both.

Qualitative research uses open-ended techniques such as observation, focus groups, and interviews to gain an understanding of customers’ basic reasons, opinions, and motivations.

• Quantitative research focuses on the generation of numerical data that can be turned into usable statistics. This kind of research most often takes the form of surveys or questionnaires that pose multiple-choice questions with predefined answers.
• Your sample refers to who you will survey and how many people you will include. In most cases, you will want a sample that reflects your target market , the population who is most likely to purchase your product.
• Depending on the type of research you conduct, your data collection methods will differ. In this course, most students conduct research through interviews (when the target population is difficult to reach or your target market is business customers) and/or surveys.

Interviews are a great method to secure open-ended answers. You might interview potential customers on what they think is the best way to communicate with them, what they like about certain competitors’ products, and get reactions to your product.

Surveys can be done by hand or through online tools such as Survey Monkey or Qualtrics. Surveys are very helpful because you can ask questions to current or potential customers about your product, competitors’ products, customer service, and any other information you may seek to create or improve your business. They are an easy way to collect large amounts of data from many customers, and they allow you to calculate responses. Online tools are particularly useful in providing repositories of data that can be later exported to other analytical tools such as Excel or SPSS.

• Once you collect your data, the next step is to make sense of it. How you analyze the data depends largely on what you want to get out of it. Typically, you will be looking for patterns and trends among the answers. Data analysis is a field unto itself, and when complex analysis is required, seeking the assistance of experts is often worth the extra cost.
• At this stage, the entrepreneur seeks to reconcile the results of their research. For example, if you were doing exploratory research about a potential product you wanted to bring to market, now would be the time to ask questions such as whether the research suggests market potential.

Entrepreneurial Marketing

On a basic level,  entrepreneurial marketing  is a set of unconventional practices that can help  start-ups and younger firms emerge and have an edge in competitive markets. The main difference between these and traditional approaches is that entrepreneurial marketing tends to focus on satisfying the customer and building trust by providing innovative products and services that disrupt or appeal to a specific market. Table 9.2 provides an overview of differences between traditional and entrepreneurial marketing.

Marketing Mix

One of the biggest misconceptions people have about marketing is that it is all about promotion, or how a company sells or advertises something. But the truth is, promotion is just one facet of the  marketing mix , which describes the basic set of strategies and approaches that marketers use to identify and reach their target market.

One common way of understanding and remembering the components of the marketing mix for products and services is by thinking in terms of the “ 7 Ps .” While each of these can be part of a company’s marketing mix, the first four relate more to products: product, pricing, promotion, and place (and traditionally have been called “the 4 Ps of marketing”). The remaining three relate more to services: physical environment, process, and people. While the 7 Ps are conceptually the same for all businesses, how a company addresses each “P” will be specific to that company’s needs and goals.

For a better understanding of the marketing mix, Figure 9.3 below breaks down the 7 Ps into their related activities.

Within the marketing mix,  product  refers to a good or service that creates value by fulfilling a customer need or desire. Goods are tangible products that can be touched, smelled, heard, and seen, such as a pair of tennis shoes, a granola bar, or a bottle of shampoo. In contrast, services are intangible products. They usually entail paying an expert to do something for you, such as car repair or house cleaning.

Companies can bundle both goods and services together to create extra value for their customers.  Birchbox , for example, provides goods (product samples) and services (customized product recommendations) to satisfy their customers’ desire to be able to buy beauty products in a hassle-free manner. The value Birchbox provides to customers relies on their ability to do both. In the United States, service-oriented businesses are increasingly playing a larger role in our local and national economies.

For start-ups, defining the value of the products they are going to offer is an important step toward identifying their competitive advantage within a marketplace. On a basic level, if you don’t know what benefit your product provides or what need it fulfills, neither will your customers. Kevin  Plank , founder of  Under Armour , knew that the value of his product would benefit many athletes who were tired of having to frequently change their wet sportswear. As a former football player, he had spent many hours training and enduring drenched practices, and wondered how he could alleviate this problem that companies didn’t address well with cotton sportswear. After college, he decided to take his idea to the next level and started a company making athletic wear that had special microfibers that kept athletes dry throughout practice and games. He then embarked on a trip to try to sell his value proposition to college football teams on the east coast. Nearing the end of 1996, he landed his first sale of shirts to Georgia Tech, which totaled $17,000—and the rest is history. Under Armour became a strong competitor to  Nike  and  Adidas  by providing a new type of athletic wear that has revolutionized performance by keeping athletes dry.

Communicating a product’s benefits to customers is a significant aspect of any marketing mix. Even if a product is the best in its class, a company must communicate this value to customers, or it will fail. This is what  promotion  does: It is the process of communicating value to customers in a way that encourages them to purchase the good or service. Promotions must have a goal, a budget, a strategy, and an outcome to measure. Companies must use their promotional budget wisely to create the best results, which can include sales, profit, and awareness through the use of a cohesive message throughout the campaign.

Some typical forms of promotion are advertising, social media, public relations, direct mail, sales promotions, and personal selling.

One of the most important and challenging elements of the marketing mix is pricing.  Price is the value that must be exchanged for a customer to receive a product or service. This is usually monetary and has a direct impact on sales. Correctly pricing your product enables your company to be competitive while maximizing your product’s profit potential.

Here are a few popular pricing models to effectively price your product:

• Subscription -The subscription model charges customers a monthly or annual fee to use its product, without regard to actual usage. One of the key benefits to this model is that the business obtains revenue up front; however, it is important for the business to monitor usage to prevent attrition. A popular example is a monthly subscription to Netflix.
• Dynamic – The dynamic model is based on supply & demand and pricing fluctuates. Uber’s rates during busy times of the day will be higher than at less popular times.
• Market-Based – The market-based model charges customers based on similar products. For example, imagine yourself in a grocery store’s laundry aisle and variety of detergents available. These products are priced within a certain acceptable range to consumers and differ only slight from their competitors.
• Pay as you go – In contrast to the subscription model, pay as you go is based on usage. Your electricity bill is calculated based on the electricity you use each month. If you don’t use it, you aren’t charged.
• Freemium – The freemium model offers a free version of the product and customers have the option to upgrade for a fee. Phone apps such as Duolingo offer free access with the option to upgrade to Super Duolingo with no ads and a more personalized experience.

Place  refers to the channels or locations—physical or digital—where customers can purchase your products; it is sometimes called  distribution . For the entrepreneur, the choice of place lies in figuring out which channels will create the most profit. In other words, which channels will reach the majority of the target market at the most efficient cost. Choosing the right  distribution channels  is one way to create a competitive advantage and generate more success for your business. Certain channels have specific capabilities such as reaching more customers, providing promotions, and providing credit.

Direct channels , such as physical or online storefronts, require no intermediaries and allow you to sell directly to consumers. For example, if you own a bakery, you would likely have a retail storefront that sells directly to consumers.

Indirect channels  require intermediaries such as distributors or sales agents to sell your products to the end customer or to other physical or online retail outlets. Indirect channels often have more than one intermediary. For example, to acquire more customers than you could reach on your own, your bakery would use indirect channels such as wholesalers or agents to get your products into local markets and grocery stores across the country. These companies would also help with logistics, which include transportation, warehousing, and handling of products.

People , or a company’s human resources, will always be a key factor in any successful business. In a service-oriented business, the people who interact with customers are especially important. Because the service  is  the product, they are the face of the brand and a direct link between the company and the customer.

When an employee delivers an acceptable or outstanding service, customers are encouraged to return to purchase the service again and also share their positive experience with others. When customers go into a jewelry store and receive good service from the salespeople, they will likely let their friends and family know about the positive experience through a personal referral or on social media.

When service is poor, customers don’t return. If customers have a bad experience at a restaurant, it is likely they will not patronize the establishment any longer and will probably share a negative review online. Sometimes, poor service has to do with factors other than employees, but as online review sites such as  Yelp  become more common, poor customer service reviews can have a devastating effect on a brand, especially for start-ups trying to break into a market. It is important to hire experienced people and have a good training system in place with rewards that will help employees deliver the best service to customers. Companies should take into consideration that no matter the size of a business, they must market not only to their customers but also to their employees, as they are the face of the company and the ones who interact with customers. Employees can make or break the brand.

Physical Environment

The  physical environment  where a service is provided is an important part of the marketing mix. It can influence the company’s image and convey a lot of information about the quality of a product, service, company, or brand. The old adage that you “get only one chance to make a first impression” is especially true for new businesses. Tangible cues—décor, smell, music, temperature, colors—send an immediate message to customers about quality and professionalism.

For example, if you walked into two dentists’ offices (remember, they are also entrepreneurs), and one office smelled and looked clean, and one did not, which one would you choose? The same goes for restaurants, retail stores, and any other physical environment. Since a service cannot be inspected before it is received, these cues help customers make their decisions.

Process  is the chain of procedures or activities required to provide a service to the customer. It is all of the activities that take place between the service provider and the customer, from beginning to end.

In the case of a doctor’s office, this would include making the appointment, filling out paperwork, waiting to be seen, seeing the doctor, and paying. Because processes can be long and involved, they need to be designed to flow as efficiently and logically as possible. In the case of services that are provided online, process includes the website’s design and functionality, and all of the steps customers take from browsing through check out. A strong website design helps the entrepreneur say what the company is about, what it does and for whom, and what actions the customer can take. Actions can range from clicking for more information, the ability to purchase a product, or checking whether there is availability for a service and being able to book it or make an appointment.

Primary vs. Secondary Sources | Difference & Examples

Published on June 20, 2018 by Raimo Streefkerk . Revised on May 31, 2023.

When you do research, you have to gather information and evidence from a variety of sources.

Primary sources provide raw information and first-hand evidence. Examples include interview transcripts, statistical data, and works of art. Primary research gives you direct access to the subject of your research.

Secondary sources provide second-hand information and commentary from other researchers. Examples include journal articles, reviews, and academic books . Thus, secondary research describes, interprets, or synthesizes primary sources.

Primary sources are more credible as evidence, but good research uses both primary and secondary sources.

Table of contents

What is a primary source, what is a secondary source, primary and secondary source examples, how to tell if a source is primary or secondary, primary vs secondary sources: which is better, other interesting articles, frequently asked questions about primary and secondary sources.

A primary source is anything that gives you direct evidence about the people, events, or phenomena that you are researching. Primary sources will usually be the main objects of your analysis.

If you are researching the past, you cannot directly access it yourself, so you need primary sources that were produced at the time by participants or witnesses (e.g. letters, photographs, newspapers ).

If you are researching something current, your primary sources can either be qualitative or quantitative data that you collect yourself (e.g. through interviews , surveys , experiments ) or sources produced by people directly involved in the topic (e.g. official documents or media texts).

Prevent plagiarism. Run a free check.

A secondary source is anything that describes, interprets, evaluates, or analyzes information from primary sources. Common examples include:

• Books , articles and documentaries that synthesize information on a topic
• Synopses and descriptions of artistic works
• Encyclopedias and textbooks that summarize information and ideas
• Reviews and essays that evaluate or interpret something

When you cite a secondary source, it’s usually not to analyze it directly. Instead, you’ll probably test its arguments against new evidence or use its ideas to help formulate your own.

Examples of sources that can be primary or secondary

A secondary source can become a primary source depending on your research question . If the person, context, or technique that produced the source is the main focus of your research, it becomes a primary source.

Documentaries

If you are researching the causes of World War II, a recent documentary about the war is a secondary source . But if you are researching the filmmaking techniques used in historical documentaries, the documentary is a primary source .

Reviews and essays

If your paper is about the novels of Toni Morrison, a magazine review of one of her novels is a secondary source . But if your paper is about the critical reception of Toni Morrison’s work, the review is a primary source .

Newspaper articles

If your aim is to analyze the government’s economic policy, a newspaper article about a new policy is a secondary source . But if your aim is to analyze media coverage of economic issues, the newspaper article is a primary source .

To determine if something can be used as a primary or secondary source in your research, there are some simple questions you can ask yourself:

• Does this source come from someone directly involved in the events I’m studying (primary) or from another researcher (secondary)?
• Am I interested in evaluating the source itself (primary) or only using it for background information (secondary)?
• Does the source provide original information (primary) or does it comment upon information from other sources (secondary)?

Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research. Tertiary sources are often used in the first, exploratory stage of research.

What do you use primary sources for?

Primary sources are the foundation of original research. They allow you to:

• Make new discoveries
• Provide credible evidence for your arguments
• Give authoritative information about your topic

If you don’t use any primary sources, your research may be considered unoriginal or unreliable.

What do you use secondary sources for?

Secondary sources are good for gaining a full overview of your topic and understanding how other researchers have approached it. They often synthesize a large number of primary sources that would be difficult and time-consuming to gather by yourself. They allow you to:

• Gain background information on the topic
• Support or contrast your arguments with other researchers’ ideas
• Gather information from primary sources that you can’t access directly (e.g. private letters or physical documents located elsewhere)

When you conduct a literature review or meta analysis, you can consult secondary sources to gain a thorough overview of your topic. If you want to mention a paper or study that you find cited in a secondary source, seek out the original source and cite it directly.

Remember that all primary and secondary sources must be cited to avoid plagiarism . You can use Scribbr’s free citation generator to do so!

Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.

Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.

Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.

Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.

To determine if a source is primary or secondary, ask yourself:

• Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
• Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
• Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?

Some types of source are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.

Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.

Always make sure to properly cite your sources to avoid plagiarism .

A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.

If you are directly analyzing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.

If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.

Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .

Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.

In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyze language and social relations (for example, by conducting content analysis or discourse analysis ).

If you are not analyzing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

Primary vs secondary research – what’s the difference.

14 min read Find out how primary and secondary research are different from each other, and how you can use them both in your own research program.

Primary vs secondary research: in a nutshell

The essential difference between primary and secondary research lies in who collects the data.

• Primary research definition

When you conduct primary research, you’re collecting data by doing your own surveys or observations.

• Secondary research definition:

In secondary research, you’re looking at existing data from other researchers, such as academic journals, government agencies or national statistics.

When to use primary vs secondary research

Primary research and secondary research both offer value in helping you gather information.

Each research method can be used alone to good effect. But when you combine the two research methods, you have the ingredients for a highly effective market research strategy. Most research combines some element of both primary methods and secondary source consultation.

So assuming you’re planning to do both primary and secondary research – which comes first? Counterintuitive as it sounds, it’s more usual to start your research process with secondary research, then move on to primary research.

Secondary research can prepare you for collecting your own data in a primary research project. It can give you a broad overview of your research area, identify influences and trends, and may give you ideas and avenues to explore that you hadn’t previously considered.

Given that secondary research can be done quickly and inexpensively, it makes sense to start your primary research process with some kind of secondary research. Even if you’re expecting to find out what you need to know from a survey of your target market, taking a small amount of time to gather information from secondary sources is worth doing.

Primary research

Primary market research is original research carried out when a company needs timely, specific data about something that affects its success or potential longevity.

Primary research data collection might be carried out in-house by a business analyst or market research team within the company, or it may be outsourced to a specialist provider, such as an agency or consultancy. While outsourcing primary research involves a greater upfront expense, it’s less time consuming and can bring added benefits such as researcher expertise and a ‘fresh eyes’ perspective that avoids the risk of bias and partiality affecting the research data.

Primary research gives you recent data from known primary sources about the particular topic you care about, but it does take a little time to collect that data from scratch, rather than finding secondary data via an internet search or library visit.

Primary research involves two forms of data collection:

• Exploratory research This type of primary research is carried out to determine the nature of a problem that hasn’t yet been clearly defined. For example, a supermarket wants to improve its poor customer service and needs to understand the key drivers behind the customer experience issues. It might do this by interviewing employees and customers, or by running a survey program or focus groups.
• Conclusive research This form of primary research is carried out to solve a problem that the exploratory research – or other forms of primary data – has identified. For example, say the supermarket’s exploratory research found that employees weren’t happy. Conclusive research went deeper, revealing that the manager was rude, unreasonable, and difficult, making the employees unhappy and resulting in a poor employee experience which in turn led to less than excellent customer service. Thanks to the company’s choice to conduct primary research, a new manager was brought in, employees were happier and customer service improved.

Examples of primary research

All of the following are forms of primary research data.

• Customer satisfaction survey results
• Employee experience pulse survey results
• NPS rating scores from your customers
• A field researcher’s notes
• Data from weather stations in a local area
• Recordings made during focus groups

Primary research methods

There are a number of primary research methods to choose from, and they are already familiar to most people. The ones you choose will depend on your budget, your time constraints, your research goals and whether you’re looking for quantitative or qualitative data.

A survey can be carried out online, offline, face to face or via other media such as phone or SMS. It’s relatively cheap to do, since participants can self-administer the questionnaire in most cases. You can automate much of the process if you invest in good quality survey software.

Primary research interviews can be carried out face to face, over the phone or via video calling. They’re more time-consuming than surveys, and they require the time and expense of a skilled interviewer and a dedicated room, phone line or video calling setup. However, a personal interview can provide a very rich primary source of data based not only on the participant’s answers but also on the observations of the interviewer.

Focus groups

A focus group is an interview with multiple participants at the same time. It often takes the form of a discussion moderated by the researcher. As well as taking less time and resources than a series of one-to-one interviews, a focus group can benefit from the interactions between participants which bring out more ideas and opinions. However this can also lead to conversations going off on a tangent, which the moderator must be able to skilfully avoid by guiding the group back to the relevant topic.

Secondary research

Secondary research is research that has already been done by someone else prior to your own research study.

Secondary research is generally the best place to start any research project as it will reveal whether someone has already researched the same topic you’re interested in, or a similar topic that helps lay some of the groundwork for your research project.

Even if your preliminary secondary research doesn’t turn up a study similar to your own research goals, it will still give you a stronger knowledge base that you can use to strengthen and refine your research hypothesis. You may even find some gaps in the market you didn’t know about before.

The scope of secondary research resources is extremely broad. Here are just a few of the places you might look for relevant information.

Books and magazines

A public library can turn up a wealth of data in the form of books and magazines – and it doesn’t cost a penny to consult them.

Secondary research from professional research agencies can be highly valuable, as you can be confident the data collection methods and data analysis will be sound

Scholarly journals, often available in reference libraries

Peer-reviewed journals have been examined by experts from the relevant educational institutions, meaning there has been an extra layer of oversight and careful consideration of the data points before publication.

Government reports and studies

Public domain data, such as census data, can provide relevant information for your research project, not least in choosing the appropriate research population for a primary research method. If the information you need isn’t readily available, try contacting the relevant government agencies.

White papers

Businesses often produce white papers as a means of showcasing their expertise and value in their field. White papers can be helpful in secondary research methods, although they may not be as carefully vetted as academic papers or public records.

Trade or industry associations

Associations may have secondary data that goes back a long way and offers a general overview of a particular industry. This data collected over time can be very helpful in laying the foundations of your particular research project.

Private company data

Some businesses may offer their company data to those conducting research in return for fees or with explicit permissions. However, if a business has data that’s closely relevant to yours, it’s likely they are a competitor and may flat out refuse your request.

Examples of secondary research data

These are all forms of secondary research data in action:

• A newspaper report quoting statistics sourced by a journalist
• Facts from primary research articles quoted during a debate club meeting
• A blog post discussing new national figures on the economy
• A company consulting previous research published by a competitor

Secondary research methods

Literature reviews.

A core part of the secondary research process, involving data collection and constructing an argument around multiple sources. A literature review involves gathering information from a wide range of secondary sources on one topic and summarising them in a report or in the introduction to primary research data.

Content analysis

This systematic approach is widely used in social science disciplines. It uses codes for themes, tropes or key phrases which are tallied up according to how often they occur in the secondary data. The results help researchers to draw conclusions from qualitative data.

Data analysis using digital tools

You can analyse large volumes of data using software that can recognise and categorise natural language. More advanced tools will even be able to identify relationships and semantic connections within the secondary research materials.

Comparing primary vs secondary research

We’ve established that both primary research and secondary research have benefits for your business, and that there are major differences in terms of the research process, the cost, the research skills involved and the types of data gathered. But is one of them better than the other?

The answer largely depends on your situation. Whether primary or secondary research wins out in your specific case depends on the particular topic you’re interested in and the resources you have available. The positive aspects of one method might be enough to sway you, or the drawbacks – such as a lack of credible evidence already published, as might be the case in very fast-moving industries – might make one method totally unsuitable.

Here’s an at-a-glance look at the features and characteristics of primary vs secondary research, illustrating some of the key differences between them.

What are the pros and cons of primary research?

Primary research provides original data and allows you to pinpoint the issues you’re interested in and collect data from your target market – with all the effort that entails.

Benefits of primary research:

• Tells you what you need to know, nothing irrelevant
• Yours exclusively – once acquired, you may be able to sell primary data or use it for marketing
• Teaches you more about your business
• Can help foster new working relationships and connections between silos
• Primary research methods can provide upskilling opportunities – employees gain new research skills

Limitations of primary research:

• Lacks context from other research on related subjects
• Can be expensive
• Results aren’t ready to use until the project is complete
• Any mistakes you make in in research design or implementation could compromise your data quality
• May not have lasting relevance – although it could fulfil a benchmarking function if things change

What are the pros and cons of secondary research?

Secondary research relies on secondary sources, which can be both an advantage and a drawback. After all, other people are doing the work, but they’re also setting the research parameters.

Benefits of secondary research:

• It’s often low cost or even free to access in the public domain
• Supplies a knowledge base for researchers to learn from
• Data is complete, has been analysed and checked, saving you time and costs
• It’s ready to use as soon as you acquire it

Limitations of secondary research

• May not provide enough specific information
• Conducting a literature review in a well-researched subject area can become overwhelming
• No added value from publishing or re-selling your research data
• Results are inconclusive – you’ll only ever be interpreting data from another organisation’s experience, not your own
• Details of the research methodology are unknown
• May be out of date – always check carefully the original research was conducted
