Determine if a backgammon program is about the same in 2011 and 2012 as it was in 1998, or if there appear to have been upgrades at some point. Also, determine whether a professor is demonstrably superior in play to the program. Key ideas: One-Way ANOVA, testing assumptions, F ratio, R2, and basic computations.
JMP features demonstrated:

5/3/2016: Fixed an error in the formula on Page 12. The denominator was changed from n-1 to k-1. Thanks for a student at the UC San Diego for pointing this out.
