Question: An experiment is performed to determine the effects of taking a statistics class on the ability to perform simple algebra problems. Ten statistics students are given a 20-item algebra test at the beginning of a statistics course, and 6 months after the course. Here are the data, which represents the number of problems completed correctly:

Student
Before After 6 Months After
1 10 11 10
2 12 14 14
3 14 20 15
4 6 10 11
5 15 16 14
6 12 14 16
7 12 15 13
8 2 7 7
9 9 10 10
10 8 18 15

Did experience with a statistics course affect algebra performance? Use the chapter’s post hoc test to make all pairwise comparisons after a significant F.
