Examples on Graphical Representation of Data. Example 1: A pie chart is divided into 3 parts with the angles measuring as 2x, 8x, and 10x respectively. Find the value of x in degrees. Solution: We know, the sum of all angles in a pie chart would give 360º as result. ⇒ 2x + 8x + 10x = 360º. ⇒ 20 x = 360º.
2: Graphical Representations of Data
A histogram is a graphic version of a frequency distribution. The graph consists of bars of equal width drawn adjacent to each other. The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. The heights of the bars correspond to frequency values. Histograms are typically used for large ...
Graphical Representation

Data representations
A circle graph (or pie chart) is a circle that is divided into as many sections as there are categories of the qualitative variable. The area of each section represents, for each category, the value of the quantitative data as a fraction of the sum of values. The fractions sum to 1 . Sometimes the section labels include both the category ...

2.1: Types of Data Representation
2.1: Types of Data Representation. Page ID. Two common types of graphic displays are bar charts and histograms. Both bar charts and histograms use vertical or horizontal bars to represent the number of data points in each category or interval. The main difference graphically is that in a bar chart there are spaces between the bars and in a ...

Alternatively, they may utilize a graph structure to illustrate relationships between entities in a knowledge graph. There are a number of ways to ...
11 Data Visualization Techniques for Every Use-Case with Examples
The Power of Good Data Visualization. Data visualization involves the use of graphical representations of data, such as graphs, charts, and maps. Compared to descriptive statistics or tables, visuals provide a more effective way to analyze data, including identifying patterns, distributions, and correlations and spotting outliers in complex ...
Data Visualization: Definition, Benefits, and Examples
Data visualization is the representation of information and data using charts, graphs, maps, and other visual tools. These visualizations allow us to easily understand any patterns, trends, or outliers in a data set. Data visualization also presents data to the general public or specific audiences without technical knowledge in an accessible ...
What Is Graphical Representation Of Data
Graphical representation of data, often referred to as graphical presentation or simply graphs which plays a crucial role in conveying information effectively. Principles of Graphical Representation. Effective graphical representation follows certain fundamental principles that ensure clarity, accuracy, and usability:Clarity : The primary goal ...
See 20 Different Types Of Graphs And Charts With Examples
A graph or chart is a graphical representation of qualitative or quantitative data. It uses different symbols such as bars, lines, columns, tables, box plots, maps, and more, to give meaning to the information, making it easier to understand than raw data.
17 Important Data Visualization Techniques
Bullet Graph. Choropleth Map. Word Cloud. Network Diagram. Correlation Matrices. 1. Pie Chart. Pie charts are one of the most common and basic data visualization techniques, used across a wide range of applications. Pie charts are ideal for illustrating proportions, or part-to-whole comparisons.
Diagrammatic Representation of Data: Bar Diagram, Line Graphs etc.
A bar graph is a graphical representation of the data in the form of rectangular bars or columns of equal width. It is the simplest one and easily understandable among the graphs by a group of people. Browse more Topics under Statistical Description Of Data. Introduction to Statistics; Textual and Tabular Representation of Data; Frequency ...
Data Representation: Definition, Types, Examples
Graphical Representation of Data: Histogram. The histogram is another kind of graph that uses bars in its display. The histogram is used for quantitative data, and ranges of values known as classes are listed at the bottom, and the types with greater frequencies have the taller bars.
Graphical Methods
Here are some characteristics of graphical methods: Visual Representation: Graphical methods provide a visual representation of data, which can be easier to interpret than tables of numbers or raw data sets. Graphs can help to reveal patterns and trends that may not be immediately apparent in the data. Simplicity: Graphical methods simplify ...
6 Inspiring Data Visualization Examples
Data visualization is the process of turning raw data into graphical representations. Visualizations make it easy to communicate trends in data and draw conclusions. When presented with a graph or chart, stakeholders can easily visualize the story the data is telling, rather than try to glean insights from raw data.
Diagrammatic and Graphic Presentation of Data
The fundamental benefits or merits of a diagrammatic and graphical representation of data are as follows: 1. To simplify the data: Outlines and charts present information in a simple manner that can be perceived by anyone without any problem. Huge volume of data can be easily presented using graphs and diagrams. 2.
What are the different ways of Data Representation?
A histogram is the graphical representation of data. It is similar to the appearance of a bar graph but there is a lot of difference between histogram and bar graph because a bar graph helps to measure the frequency of categorical data. A categorical data means it is based on two or more categories like gender, months, etc. Whereas histogram is ...
Advantages and Disadvantages of Graphical Representation of Data
4. Lack of Secrecy: Graphical representation makes the full presentation of information that may hamper the objective to keep something secret. 5. Problems to select a suitable method: Information can be presented through various graphical methods and ways. Which should be the suitable method is very hard to select.
