## Students will review:

This chapter helps students review the concepts in a data analysis, statistics and probability unit of a standard SAT prep course. Topics covered include:

- Bar graphs and pie charts
- Geometric sequences
- Mean, median and mode
- Permutations
- Probability of independent and dependent events
- Either/or probability
- Probability of combinations and permutations
- Factorials
- Math combinations

### 1. 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.

### 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. Identifying and Calculating Averages on the SAT

In this lesson, we'll take the fear out of averages with a simple explanation and a pattern that you can use to make any average problem simple, even the weighted averages.

### 4. What is Categorical Data? - Definition & Examples

Categorical data is one of two types of data that you can collect when conducting research. This lesson will teach you how to understand and use categorical data.

### 5. The Purpose of Statistical Models

Understanding statistics requires that you understand statistical models. This lesson will help you understand the purpose of statistics, statistical models, and types of variables.

### 6. What are Center, Shape, and Spread?

Center, shape, and spread are all words that describe what a particular graph looks like. Watch this video lesson to see how you can identify and explain each.

### 7. Defining the Difference between Parameters & Statistics

Using data to describe information can be tricky. The first step is knowing the difference between populations and samples, and then parameters and statistics.

### 8. What is a Two-Way Table?

Do you believe in Martians? Do you watch football on television? A Two-Way Table or Contingency Table is a great way to show the results of all kinds of survey questions. In this video we will learn how to read a two-way table.

### 9. How to Calculate Percent Increase with Relative & Cumulative Frequency Tables

In statistics, one way to describe and analyze data is by using frequency tables. This lesson will discuss relative and cumulative frequencies and how to calculate percent increase using these two methods.

### 10. Probability of Simple, Compound and Complementary Events

Simple, compound, and complementary events are different types of probabilities. Each of these probabilities are calculated in a slightly different fashion. In this lesson, we will look at some real world examples of these different forms of probability.

### 11. How to Use Scatter Plots to Solve Word Problems

Watch this video lesson to learn how you can use a scatter plot to help you solve a word problem. You will see how easy it becomes to solve your problem once you have your scatter plot.

### 12. Exponential Growth vs. Decay

How is it that it only takes four years for our computer to go from top-of-the-line to almost worthless? Well, it has something to do with what's called exponential decay, which we'll learn about here!

### 13. Data Analysis: Purpose & Steps

In this lesson, the student will learn what is data analysis, the purpose of data analysis, and the steps to conduct a data analysis. Also in this lesson, the student will learn how to organize, interpret, and represent data.
