RESEARCH STUDY 13.4
Dr. Tropez conducts a study examining the relationship between exposure to religion in popular media and religiosity (defined as "the belief in and worship of a superhuman controlling power, especially a personal God or gods"). In his study, he randomly samples a group of 113 participants from his local community college. He generates a list of movies with religious themes (Year One, Dogma, Passion of the Christ) and asks participants to indicate how many they have seen. He then measures religiosity by asking participants how many times they have attended a house of worship (e.g., church, temple, synagogue, mosque) in the past year. He finds that having seen a higher number of religious-themed films is positively correlated with religious attendance.
-Refer to Research Study 13.4 above to answer the following question.
What is the difference between theory-testing mode and generalization mode? In which mode does Dr.Tropez seem to be operating?
