The data in Exercises 16.7 and 16.11 both produced a significant F. Do you have more or less faith in one of these effects? Why?
Exercise 16.7
Foa, Rothbaum, Riggs, and Murdock (1991) conducted a study evaluating four different types of therapy for rape victims. The Stress Inoculation Therapy (SIT) group received instructions on coping with stress. The Prolonged Exposure (PE) group went over the events in their minds repeatedly. Those in the Supportive Counseling (SC) group were taught a general problemsolving technique. Finally, the Waiting List (WL) control group received no therapy. Data with the same characteristics as theirs follow, where the dependent variable was the severity rating of a series of symptoms.
