Statistics: Chapter 3 Correlations

The kids worked on TI84 graphing exercises on p.186 and p.219 before class began.  (They're doing the same exercises again as homework to ensure the kids can do the exercise.)  (The variables are located in Vars Statistics or Y-Vars Functions.)  We went over half the slides in Mrs. Daniel's powerpoint 3.1--just before the formula to calculate r, correlation coefficient.  The kids can enter data in the stat function of the graphing calculator, calculate linreg, and graph linreg.  We reviewed those skills last time.  Be sure to practice entering data and graphing.
