Question 2

Twenty people were selected to participate in a psychology experiment. They answered a short multiple-choice quiz about their attitudes on abortion and then viewed a 50-minute film. The following day the same 20 people were asked to answer a follow-up questionnaire about their attitudes. At the completion of the experiment, the experimenter will have two sets of scores. Do these two samples represent dependent or independent samples? Explain.
