## Students will review:

This chapter helps students review the concepts in a data, statistics, and probability unit of a standard high school algebra I course. Topics covered include:

- Finding the probability of independent and dependent events
- Calculating mean, median, mode, and range
- Organizing and understanding data with tables and schedules
- Understanding bar graphs and pie charts

### 1. Probability of Independent and Dependent Events

Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.

### 2. How to Calculate Mean, Median, Mode & Range

Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.

### 3. Organizing and Understanding Data with Tables & Schedules

In math, when we have to deal with a lot of data, having a visual format to present all the data becomes very useful. Watch this video lesson to learn how you can take advantage of two of these visual formats.

### 4. Understanding Bar Graphs and Pie Charts

In this lesson, we will examine two of the most widely used types of graphs: bar graphs and pie charts. These two graphs can provide the reader with a comparison of the different data that is displayed.

### 5. Binomial: Definition & Examples

Binomial is a little term for a unique mathematical expression. Learn what makes binomials so special, how to easily identify them, and the mathematical operations that can be performed on them. After the lesson, test yourself with a quiz.

### 6. Standard Normal Distribution: Definition & Example

In this lesson, you will learn about the properties of the standard normal distribution and why it is so important to the field of statistics. A real life example will be used to illustrate this value.

### 7. What is Probability in Math? - Definition & Overview

Remember throwing a quarter and calling out heads or tails? Learn what this has to do with probability. Also learn how you can use your newly-learned skills from this lesson to help you decide whether you should play heads or tails at all!

### 8. What is Standard Deviation? - Definition, Equation & Sample

This lesson will examine the concepts of standard deviation and variance. It will examine the formula for standard deviation and show how to calculate it for both a population and a sample of a population.

### 9. What is the Range of a Function? - Definition & Examples

In this lesson, we will learn what the range of a function is. We will also see how to find the range of a function in different examples. When you are finished with the lesson, you can take a quiz to test your knowledge.
