We started the day by looking at the graphs for both our M&M data, as well as the Starbucks data. Make sure you know how to plot data on your calculator, find the regression line, and understand how to put that information back into the context of the problem. This material WILL be on the midterm.

We discussed 4 different types of Variation: Direct, Inverse, Exponential, and Joint. Be sure that you know the equations and standard shape of these relationships. If you still have questions, check out the links to the right.
