A study compares the effects of three experimental treatments, A, B, and C, by giving each treatment to 16 participants and then assessing their performance on a standard measure. The results on the standard measure are as follows. Treatment A group: M = 20, S2 = 8; Treatment B group: M = 22, S2 = 9; Treatment C group: M = 18, S2 = 7. Using the .01 significance level, do the three experimental treatments create any difference among the...

3. Suppose you are a researcher studying treatments for depression. Imagine three treatment groups (anti-depressant, therapy, and placebo) are being compared using Analysis of Variance. What effect would each of the following have on an F score (make it smaller, make it larger, or cause no change)? Explain why. (Note: If you have trouble, look at the slides and consider the formula F = variance between groups/variance within groups, and consider what would influence that ratio). a. A large within-group...
