Question: Living on campus. A February 2, 2008, article in the Columbus Dispatch reported a study on the distances students lived from campus and average GPA. Here is a summary of the results:
Residence Avg. GPA
Residence hall 3.33
Walking distance 3.16
Near campus, long walk or short drive 3.12
Within the country, not near campus 2.97
Outside the country 2.94
Based on these data, is the association between the distance a student lives from campus and GPA positive, negative, or near 0?
