A psychologist wants to see how effective 3 different treatments are on depression. One group gets medication only, one group only gets counseling, and one group only receives a diet supplement. Depression scores after the treatments are listed below:

Medication	Counseling	Diet Supplement
23	38	40
16	32	28
15	29	33
32	42	42
26	25	35

Use the .05 level of significance, state your research question, critical value, include your ANOVA Source Table and calculations, and state whether you retain/reject the null hypothesis

Use Tukey’s HSD test (α = .05) as a follow-up to determine the pattern of differences among the means. Show your calculations and write a few sentences interpreting the differences between the three groups.
