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, after completing the course, and 6 months after the course. Here are the data, which represent 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 |
| 0 | 8 | 18 | 15 |
Did experience with a statistics course affect algebra performance? Use the chapter’s post hoc tests to make all pair wise comparisons after a significant F.
