In this lesson, you will find and interpret the correlation coefficient and use it to understand the strength of a linear relationship.

When you finish this lesson, you will be able to:

• Describe the “goodness of fit” of a linear model using the correlation coefficient.
• Match the correlation coefficient with a scatter plot and linear model.

Here are the activities that will help you reach those goals:

• 3.4.1: Compare Scatter Plots with Linear and Nonlinear Trends
• 3.4.2: Scatter Plot Differences and Connections to Correlation Coefficient
  • 3.4.2: Self Check
