Specifically, the researcher wanted to see if there is a relationship between the location of a person's relationship partner and whether the person is still in a relationship at the end of the person's first semester of college. A questionnaire was administered to a group of incoming freshman students one month prior to leaving home to begin their first semester at a four-year college. Some of the students had dating partners that lived near the college the student would be attending, and others had dating partners that lived a long way away from the college. The researchers then contacted the participants again late in the fall semester, asking them about the current status of their relationship. Below the results that were found.
