Question
Researchers were interested in assessing the effects of a new treatment on seasonal affective disorder. Mood was assessed in all participants at three time-points: (1) pre-treatment (0 weeks), (2) after 2 weeks of treatment, and (3) after 4 weeks of treatment.
| Subject | 0 weeks | 2 weeks | 4 weeks | Mparticipant |
| 1 | 28 | 45 | 69 | 47.33 |
| 2 | 32 | 43 | 72 | 49 |
| 3 | 30 | 47 | 65 | 47.33 |

| 5 | 31 | 44 | 70 | 48.33 |
| M | 30 | 44.8 | 70.2 | GM = 48.33 |
What is the SSwithin (i.e., SSerror)? Round to 2 decimal places.
Hint: Σ(X - GM)2 = 4207.33, Σ(M- GM)2 = 4133.73, Σ(Mparticipant - GM)2 = 12.67
