Instructional Ideas

• Form collaborative groups to complete the exercises in the lesson; monitor scholars to identify and misconceptions, and to ensure understanding

Classroom Considerations

• Begins as an extension of the previous lesson in the series
• Learners should already have experience with regression equations

Pros

• Encourages learners to try different models to determine the best regression model for the data
• Provides both guided and independent practice problems with answer keys

Cons

• None
