<p>I don’t think that many North Carolineans come to Virginia for College. The largest OOS students come from NJ, NY, MA, and PA I believe, and I don’t think any individual one of those is above 3% of the student population, so it clearly cannot be 3/4ths if only 2/3rds of the students are from instate (and even then, VA, like NC, is quite diverse. Blacksburg =/= Arlington). It is a sizable and statistically significant difference, but you are correct in that it is up to the poster to determine what importance that it has for him.</p>
