Questions to be Sure to Include

Integrate review questions into this test. This includes questions that ask students to

use a model to make predictions

calculate and interpret a residual

interpret a residual plot

interpret slope and yintercept in context

analyze residual plots

interpret r and rsquared

interpret s


Questions that ask students to use regression computer output to:

find a linear or nonlinear model of best fit

make a prediction

calculate a confidence interval for slope

perform a significance test for slope


In the free response, consider using one context to have students do both a confidence interval and a significance test for slope. Provide students with regression computer outlet so that they have SEb.
Tips to Give Your Students

Close reading and careful writing are critical to your success this year.

Be sure to answer all parts of each question.

There is a difference between a residual plot and a dotplot of residuals.

Use the 4step process for inference. At this point, you are well trained!

Know your inverse transformations (log and natural log)
