In this lesson, you will assess the fit of a function by plotting and analyzing residuals.

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

• Plot and calculate residuals for a data set and use the information to judge whether a linear model is a good fit.

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

• 3.3.1: Subtracting an Estimated Value from an Actual Value
• 3.3.2: Plotting and Analyzing Residuals
  • 3.3.2: Self Check
  • 3.3.2: Additional Resources
• 3.3.3: Matching Residuals Graphs to Scatter Plots
  • 3.3.3: Self Check
  • 3.3.3: Additional Resources
• 3.3.4: Identifying Best Fit Line for Residuals on a Graph

After that, you’ll practice and review.

• 3.3.5: Practice
• 3.3.6: Lesson Summary
