Objective: Use graphing calculator technology to create and compare multiple regressions for the same data set.
Other needs: M&Ms or Skittles, plastic cup for students to drop the candy
This is a fun activity to introduce exponential functions with technology. Students perform an experiment in dropping candy to create data points that can be entered in a graphing calculator to find multiple regression equations, and then choose the one they feel is the best fit. It's a great way to incorporate comparisons of different types of functions. You could use this in Algebra II, Pre-calc, or College Algebra
Hints in the handout are guided towards use of the TI-83+ or TI-84+ family of calculators.
