# Ch 40: Regression and Correlation

Use this chapter to learn about regression and correlation in geometry. These video lessons and online quizzes cover several techniques used in describing and analyzing data.

## Regression and Correlation - Chapter Summary

The lessons in this chapter provide you with a thorough look at ways to organize and display data. You'll learn how to determine the best way to display data, and get information on using methods such as scatter plots, stem-and-leaf plots, tables and pie charts. Another lesson will show you what correlation is and how to interpret it in research results. You'll explore methods of distinguishing between correlation and causation, and look at the correlation coefficient.

In other lessons, you'll practice using data in interpreting linear relationships. Transforming non-linear data is also explained. By the end of this chapter, you should be informed about topics that include:

• Creating and interpreting scatter plots
• Fitting a line with simple linear regression
• Analyzing residuals
• Interpreting the slope and intercept of a linear model
• The correlation coefficient
• Interpreting correlations in research results
• Interpreting linear relationships using data

These brief, engaging geometry videos are presented by experienced instructors who use real life examples to illustrate their topics. Practice lessons allow you to test your knowledge of what's been covered, and all these lessons have multiple-choice quizzes at the end. The questions in the quizzes link back to the videos, allowing you to review important concepts and passages. There's also a complete written transcript of every video lesson, which allows you to read through the lesson in addition to watching the video.
