This activity is a jigsaw where the students are broken into home groups and expert groups. There are five different regression models (so 5 expert groups) which each contain a data set, a scatterplot (to be printed on cardstock) and a scenario. Students should determine which type of regression model is represented and come up with an explanation that supports both the scenario and the scatterplot. The students will then input the data into their calculators and find the regression equation. Once this is completed in their expert groups students will return to their home groups and teach their group.
