Question 214.5 pts

You must show all work, including formulas, calculations with intermittent steps that are organized, legible, with the final answers circled or boxed for easy reference for credit.

Dr. Allison looks for factors that affect thinking. In one study, she had three groups of participants work on seven remote association problems, which require creative thinking. One group prepared for the task by exercising, a second group watched a comedy video, and the third group was a control group that simply began working on the problems. The scores below show the number correct answers for each participant. The higher number, the more creative thinking shown by the groups. Perform an ANOVA, compile a summary table, find f, and calculate HSD values and its effect size d and write a complete interpretation thereof. (Hint: See what you are given, then calculate what you need)
