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 y-intercept in context
-
analyze residual plots
-
interpret r and r-squared
-
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 4-step process for inference. At this point, you are well trained!
-
Know your inverse transformations (log and natural log)
