Lab # 9 Statistics in Psychology
Analysis of Variance Within Subjects
ANOVA One-Way Within-Subjects Design
1. A group of clinicians who are members of the U.S. military are concerned with the morale of troops
serving in war regions. They hypothesize that the number of tours a soldier has served significantly
affects morale. To test this hypothesis, they select a sample of eight soldiers who served three tours in
war regions and ask them to rate their morale during each tour they served in. Lower ratings indicate
lower morale. The table lists the hypothetical results of this study. Complete the F table and make a
decision to reject or fail to reject the null hypothesis at the .05 significance level.
