A random sample of students was studied. Whether the student
chose to sit in the front, middle, or back row in a college class
was recorded, along with the person’s GPA. The results of an ANOVA
gave F=7.47 and p=.003.
Would it make sense to do a post-hoc procedure in this case?
Assuming it does, the Tukey tests give the following results
