A social psychologist is comparing the perceived harshness of five crimes. He has produced videotaped re-enactments of the crimes and is asking viewers to give their prison sentence judgments. A prison sentence judgment is the number of months in prison a viewer thinks the crime's perpetrator should get as punishment. For one particular study, the psychologist chose 20 adults at random to be viewers. He asked each adult to watch each crime re-enactment and give a prison sentence judgment for each. (Thus, each adult gave a prison sentence judgment for all five crimes.)After checking that the assumptions for the test were satisfied, the psychologist performed a one-way, repeated-measures ANOVA test to compare the prison sentence judgments for the five crimes.
