Calculate the sums of squares for the difference scores below. Eight people were measured twice. Subtract it T2 - T1 (this way an increase will be a positive score, a decrease will be a negative score). Be careful of positive and negative values when you are calculating differences and adding them to get the mean difference.
Baseline T1 | Test T2 |
14 | 11 |
18 | 6 |
5 | 15 |
12 | 9 |
22 | 21 |
3 | 4 |
17 | 20 |
