Circuit Training - Statistics - Exploring Two-Variable Data

I wrote this circuit as a review for the end of Unit 2 of the AP Statistics curriculum. It involves mainly linear regression but also some two-way tables. If you have never used a circuit before, I encourage you to read the directions carefully and work the entire set of exercises, in order, ahead of your students. The answers are imbedded in the circuit; it is how students will move from one question to the next. I am pretty sure there are no mistakes, but if you suspect an error, please email me virge@virgecornelius.com.
