Question 14.11
14.11 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 county, not near campus |
2.97 |
| Outside the county | 2.94 |
Based on these data, is the association between the distance a student lives from campus and average GPA positive, negative, or near 0?
