### 1. 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.

### 2. Measures of Dispersion and Skewness

Watch this video lesson to learn how you can describe your data using two different statistical characteristics. Learn what it means for your graph to have variability and what it means for your graph to be skewed.

### 3. Normal Distribution: Definition, Properties, Characteristics & Example

In this lesson, we will look at the Normal Distribution, more commonly known as the Bell Curve. We'll look at some of its fascinating properties and learn why it is one of the most important distributions in the study of data.

### 4. Regression Analysis: Definition & Examples

Watch this video lesson to learn about regression analysis and how you can use it to help you analyze and better understand data that you receive from surveys or observations. Learn what is involved in regression analysis and what to look out for.

### 5. 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.

### 6. 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.

### 7. Classical Probability: Definition, Approach & Examples

In this lesson, you will learn about classical probability, its formula, and how to convert probability to percentages. You will have a chance to practice your new-found skills with several examples.

### 8. Empirical Probability: Definition, Formula & Examples

In this lesson, we're going to explore empirical probability. We'll become familiar with the definition, look at some examples, and use the formula for empirical probability to become comfortable calculating these types of probabilities.

### 9. Independent Events: Definition, Formula & Examples

This lesson will define independent events, give several scenarios in which they occur, provide the formula for finding the probability of these types of events, and explain how to use the formula.

### 10. Law of Large Numbers: Definition, Examples & Statistics

In this lesson, we'll learn about the law of large numbers and look at examples of how it works. We'll also see how businesses use the law of large numbers to do things like set insurance premiums. A short quiz will follow the lesson.
