Understanding Graphs & Charts - Chapter Summary
What is a pie chart? A stacked bar chart? A two-way table? Using this chapter, you will be able to identify these and other types of graphs and charts. These lessons will explore how to create these charts and graphs and how to analyze or interpret data derived from them. After successfully completing your study of this chapter, you should be able to perform the following tasks:
- Provide details about the aspects of pie charts and bar graphs
- Define and understand the uses for stacked bar charts
- Compare data obtained from two or more pie charts
- Make and read box-and-whisker plots
- Relate the uses of scatterplots and line graphs
- Interpret information on line and bar graphs
- Describe the information related by a two-way table
- Create frequency charts and cumulative frequency tables
- Discuss types of frequency distributions
Our lessons are easily accessible at any time, on any internet-accessible device, so you can learn at your own pace. You can also print lesson transcripts and have them handy as quick reference tools. Determine how much you have retained or whether you need to continue your review of this material by taking self-assessment quizzes after each lesson.
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. What is a Stacked Bar Chart?
A stacked bar chart is a visual representation of data. In this lesson, you will learn how to recognize stacked bar charts and explore examples of their practical uses. A brief quiz is included to allow you to test your understanding.
3. What is a Pie Chart? - Definition & Examples
Learn how useful pie charts can be in your life and how you can gain information by just glancing at one. Look over some examples, learn how to create pie charts yourself, and then take a short quiz.
4. Comparing Pie Chart Data
Pie charts contain a lot of data. Complete this lesson and learn how to visually compare two pie charts to evaluate two situations without having to look at the individual data values.
5. Read, Interpret & Construct Box-and-Whisker Plots
Box-and-whisker plots may be different than the other graphs you've learned about. Instead of showing the quantity of data, they help us figure out how spread out a set of data is. Learn how to make and read one, then test your skills with a short quiz.
6. Scatterplots and Line Graphs: Definitions and Uses
After watching this video, you will be able to understand scatter plots and line graphs. You will also be able to use them to tell people a story about what you see and observe. You will also be able to read them.
7. Interpreting Graphical Representations
After watching this video lesson, you will be able to quickly and easily read and interpret any line and bar graph. You will be able to gather important information by just looking at one of these graphs.
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 Create Frequency Charts
Frequency charts allow us to quickly figure out how many times a specific event has happened. As you can imagine, this is very useful for everything from figuring out who ate the most pizza to finding the median of a group of scores.
10. Cumulative Frequency Tables: Definition, Uses & Examples
Cumulative frequency tables can help you analyze and understand large amounts of information. In this lesson, you practice creating and interpreting cumulative frequency tables.
11. Frequency Distributions: Definition & Types
This lesson explores the process of creating frequency distributions and histograms to give readers of your future scientific articles a numerical or visual way to understand the data you have presented.
