Question
What is the turkey HSD for week 0 and week 4 comparison?
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 | M_participant | |---------|---------|---------|---------|--------------| | 1 | 28 | 45 | 69 | 47.33 | | 2 | 32 | 43 | 72 | 49 | | 3 | 30 | 47 | 65 | 47.33 | | 4 | 29 | 45 | 75 | 49.67 | | 5 | 31 | 44 | 70 | 48.33 | **M**: - 0 weeks: 30 - 2 weeks: 44.8 - 4 weeks: 70.2 **GM = 48.33** **Explanation:** The table records mood scores of five subjects assessed over three time points: before treatment (0 weeks), after two weeks, and after four weeks of treatment. Each subject has their own mean (M_participant) calculated across these assessments. Additionally, the mean mood score (M) across all participants is provided for each time point, showing that mood improves as the treatment progresses. The grand mean (GM) averages the means of all subjects.
