# Ch 47: 6th-8th Grade Math: Data & Graphs

### About This Chapter

## 6th-8th Grade Math: Data & Graphs - Chapter Summary

Middle schoolers use the short, information-packed video lessons in this math chapter to strengthen their skills in working with data and graphs. By making their way through the material, your 6th, 7th or 8th grader will learn how to create and interpret a variety of tables, charts and graphs. Instructors use examples to teach students about pie charts, line graphs, stem-and-leaf plots, bar graphs, frequency charts and more. Students also find out how to read circle graphs and measure a circle's central angle. If your middle schooler needs extra support, he or she can study lesson transcripts and submit questions to instructors. Students can check their understanding of data and graphs by taking multiple-choice lesson quizzes and the chapter exam.

### 1. 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.

### 2. Using Tables and Graphs in the Real World

We use tables and graphs in algebra as ways to visually show an equation or function. But do we really use these in the real world? Is it that important to learn about tables and graphs? Find out in this video lesson.

### 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. Reading & Interpreting Stem-and-Leaf Plots

Stem-and-leaf plots? No, we are not going to study plants. In this lesson, you will learn what a stem-and-leaf plot is, how to read one, and how to interpret it. You will become a pro in no time!

### 5. 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.

### 6. Creating & Interpreting Scatterplots: Process & Examples

Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.

### 7. 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.

### 8. 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.

### 9. Reading & Interpreting Pictographs

Imagine reading chart after chart of the same dry information. Now imagine if that information could be presented with images and in only one chart. Much better, right? That's exactly what pictographs allow us to do.

### 10. Reading & Interpreting Circle Graphs & Central Angles

Circle graphs are some of the most useful graphical descriptions of data around. However, without knowing how to find central angles, their usefulness is limited, and their creation is difficult. In this lesson, we learn how to find central angles while using and creating circle graphs.

### 11. 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.
