- Interpret and read line graphs
- Create and interpret histograms, box plots and dot plots
- Describe pie charts and bar graphs
- Read and create stem and leaf displays
- Use a circle graph to share data
- List types of bar graphs
- Share data with double bar graphs and double line graphs
All the lessons are available around-the-clock via any computer or mobile device and can be viewed as short videos or full transcripts. Mini quizzes paired with the lessons can quickly and easily test your knowledge of interpreting and graphing data. The Dashboard keeps track of your progress through this chapter and lets you submit lesson questions to our experts.
1. 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.
2. 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.
3. 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.
4. Creating & Interpreting Histograms: Process & Examples
Creating histograms can help you easily identify and interpret data. This lesson will give you several examples to better understand histograms and how to create them.
5. Creating & Interpreting Box Plots: Process & Examples
Box plots are an essential tool in statistical analysis. This lesson will help you create a box plot and understand its meaning. When you are finished, test your understanding with a short quiz!
6. Creating & Interpreting Dot Plots: Process & Examples
Dot plots are a visual way to display the frequency distribution in a data set. In this lesson, you will learn how to construct a dot plot and understand its uses.
7. 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.
8. Creating & Reading Stem & Leaf Displays
Every once in a while you will come across stem-and-leaf displays in statistics. These displays can be very useful in identifying all of the values in a data set while still visually representing the data.
9. Circle Graph: Definition & Examples
A circle graph is a circular chart divided into sections that each represent a percentage of the total. This lesson will define a circle graph and give some examples of types of circle graphs.
10. Bar Graph: Definition, Types & Examples
A bar graph is a mathematical representation of data. In this lesson, you will learn the definition of a bar graph, including how to recognize the different types of bar graphs. You will also learn how to create bar graphs.
11. Double Bar Graph: Definition & Examples
We will explore the function and examples of a double bar graph. Also in this lesson you will learn to create questions and interpret data from a double bar graph.
12. Double Line Graph: Definition & Examples
We will explore the function and examples of a double line graph. In this lesson, you will also learn to create questions and interpret data from a double line graph.
