Also included in.

Description

This Probability and Statistics Unit Bundle includes guided notes, homework assignments, two quizzes, a study guide and a unit test that cover the following topics:

• The Fundamental Counting Principle

• Permutations

• Combinations

• Theoretical Probability

• Probability of Independent and Dependent Events

• Conditional Probability

• The Binomial Theorem

• Binomial Probability

• Measures of Center: Mean, Median, Mode

ADDITIONAL COMPONENTS INCLUDED:

(1) Links to Instructional Videos: Links to videos of each lesson in the unit are included. Videos were created by fellow teachers for their students using the guided notes and shared in March 2020 when schools closed with no notice.  Please watch through first before sharing with your students. Many teachers still use these in emergency substitute situations. (2) Editable Assessments: Editable versions of each quiz and the unit test are included. PowerPoint is required to edit these files. Individual problems can be changed to create multiple versions of the assessment. The layout of the assessment itself is not editable. If your Equation Editor is incompatible with mine (I use MathType), simply delete my equation and insert your own.

(3) Google Slides Version of the PDF: The second page of the Video links document contains a link to a Google Slides version of the PDF. Each page is set to the background in Google Slides. There are no text boxes;  this is the PDF in Google Slides.  I am unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

Unit 11 – Probability

Probability, or the measurement of chance, is a challenging topic for students and teachers alike.  For the first time, the disparate topics of combinatorial probability and binomial probability occur in the same course.  The development in this unit first seeks to familiarize students with counting techniques and then use these techniques for probability calculations.  Then, binomial probability is emphasized in two lessons, including problems involving at least and at most scenarios.  Finally, the binomial expansion is discussed.

Final answer:

Unit 11 of probability and statistics involves understanding concepts like random sampling, probability calculations, and different statistical distributions. You use these concepts for the calculations and evaluations in your homework. This guide is only a primer to those concepts, actual calculations depend on the specific problems given.

Explanation:

In Unit 11, probability and statistics, the concepts of random sampling , probability calculations , and statistical distribution such as Binomial, Poisson, and Normal distributions are taught. Let's tackle these concepts based on the provided material.

• Random Sampling: A random sample is a subset of individuals chosen from a larger set. For example, if you have six sets of quiz scores and want to generate different types of samples, you will use a random number generator.
• Probability is the mathematical tool used for studying randomness, like the chance of an event occurring. The problem given for Probability calculation was not fully provided but usually it will involve finding the likelihood of a particular value or range of values with a given data set.
• Statistical Distribution: It is a listing of all possible values of a statistical variable, and how often each value occurs. For instance, the Poisson distribution can be used if the probability of success is small and the number of trials is large. Such distribution can be represented like U(24, 26) or N(25, 0.0577). And mean and standard deviation provide information on the central tendency and dispersion of the distribution.

In practice, this knowledge can be used to evaluate whether collected data fit certain distributions such as uniform or exponential.
