Calculating & Interpreting Statistical Data - Chapter Summary
Statistical math operations are often used to evaluate data in science, business and education as well as math. In these lessons, you will learn what quantitative data is and how to perform common statistical calculations like mean and median. But, what do all those numbers mean? How do you share them with others in a way they will make sense? With graphs, charts and tables! You'll learn all about them as you watch each video lesson. By the time you have completed the lessons in this chapter, you'll understand:
- Mean, median, mode and range
- Two-way and frequency tables
- Identifying quantitative data
- Histograms in math
- Line graphs, bar graphs and pie charts
Our knowledgeable instructors make learning fun and easy with short video lessons full of great examples.

Learning couldn't be easier!
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. What is a Frequency Table? - Definition & Examples
In this lesson, learn what a frequency table is and view a few examples of situations in which frequency tables would be useful. Then, test your knowledge with a brief quiz.
3. What is Quantitative Data? - Definition & Examples
Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.
4. What is a Histogram in Math? - Definition & Examples
Watch this video lesson to see how useful a histogram can be when you need to show a bunch of data in an easy to read format. Also, learn how you can easily gather the information you need from looking at a histogram.
5. Reading and Interpreting Line Graphs
Watch this video lesson to find out how useful line graphs can be and how much information you can gain just from looking at one. Learn how you can apply that information in your own life to help you make better decisions.
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. 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.
