Ch 21: Algebra II: Statistics

About This Chapter

Our Algebra II: Statistics chapter can show you how to calculate various measures of dispersion and interpret statistical charts. Keep reading for more information on what you'll learn through this chapter's easy-to-understand video lessons.

Algebra II: Statistics - Chapter Summary and Learning Objectives

Our chapter on statistics can introduce you to several different statistical dispersion terms, including the mean, median, mode and range. You'll also learn about important measures of distribution and the properties of the normal curve. Practice examples can show you how to organize and read data presented on charts, graphs and tables. Upon completion of the chapter, you should have a good understanding of the following subjects:

  • Mean, median, mode and range
  • Variability and skewness
  • Normal distribution
  • Regression analysis
  • Statistical data organization and interpretation

How to Calculate Mean, Median, Mode & Range

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.

Measures of Dispersion and Skewness

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.

Normal Distribution: Definition, Properties, Characteristics & Example

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.

Regression Analysis: Definition & Examples

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.

Organizing and Understanding Data with Tables & Schedules

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.

Understanding Bar Graphs and Pie Charts

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.
