Ch 20: Data Interpretation in Math

About This Chapter

Use the lessons in this chapter to develop a strong understanding of data interpretation in math. Feel confident that you grasp concepts that include extrapolation, simple linear regression and dot plot interpretation.

Data Interpretation in Math - Chapter Summary

Interpreting data in math can feel complicated if you don't understand the concept. This chapter can help you grasp the processes involved in data interpretation. Lessons also help you examine dot plots, histograms, line graphs and other data interpretation tools. Upon completion of the lessons, you will be ready to do the following:

  • Define and share uses of histograms, scatterplots and line graphs
  • Demonstrate the process of creating and interpreting dot and box plots
  • Read and create stem and leaf displays
  • Interpolate and extrapolate a line graph
  • Find the regression line of a set of data
  • Solve problems using linear regression
  • Provide the meaning of misleading graphs

Developed by top instructors, the video and text lessons in this chapter make learning about data interpretation fun and easy. Review the lessons anytime from your computer, smartphone or tablet, and use short lesson quizzes to test your knowledge. A chapter exam is available to gauge your understanding of lesson concepts in a more comprehensive manner. If you need additional details about any lesson topic, be sure to submit your questions to our experts.

What is a Histogram in Math? - Definition & Examples

1. 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.

Creating & Interpreting Dot Plots: Process & Examples

2. 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.

Creating & Interpreting Box Plots: Process & Examples

3. 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!

Scatterplots and Line Graphs: Definitions and Uses

4. 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.

Creating & Reading Stem & Leaf Displays

5. 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.

Extrapolation & Interpolation with Line Graphs

6. Extrapolation & Interpolation with Line Graphs

After watching this video lesson, you should be able to interpolate and extrapolate a line graph based on just a few points. You will be able to provide data points that haven't been given to you.

Simple Linear Regression: Definition, Formula & Examples

7. Simple Linear Regression: Definition, Formula & Examples

Simple linear regression is a great way to make observations and interpret data. In this lesson, you will learn to find the regression line of a set of data using a ruler and a graphing calculator.

Problem Solving Using Linear Regression: Steps & Examples

8. Problem Solving Using Linear Regression: Steps & Examples

Linear regression can be a powerful tool for predicting and interpreting information. Learn to use two common formulas for linear regression in this lesson.

Misleading Graphs: Definition & Examples

9. Misleading Graphs: Definition & Examples

In this lesson, you'll learn the definition of misleading graphs and explore some examples to see how and why they are produced. Following the lesson, you'll have a chance to test your own understanding of misleading graphs.
