Dr Tropez Conducts a Study Examining the Relationship Between Exposure

Essay

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.
Provide an example of each of the following for Dr. Tropez's original study: a direct replication, a conceptual replication, and a replication with extension.
