This Calculating Residuals and Constructing a Residual Plot lesson plan also includes:
Start this instructional activity by having your class generate their own data and determine the line of best fit relating their height and shoe size. Interpret the meaning of the slope and y-intercept in the context of the problem and use the equation to estimate shoe size based on height. Discuss the accuracy of their model and introduce the concept of residuals. Follow up with a two-problem worksheet where learners can practice calculating residuals for given data sets. The first has a step-by-step guide to the process. Included on the handout are directions on how to graph residuals on a TI calculator.
