Explanation / Answer

Correct Answer:

A

Test the null hypothesis that there is no difference in mean depression scores across groups by regressing depressing score against dummy variables for T1, T2, T3, and T4, and using global F test.

Explanation:

We know that we use ANOVA F test for checking the significant difference in more than two population means and for the given scenario we have to compare more than two average depression scores. Here, we have to compare four average depression scores and then we have to test whether there is any significant difference in these four average depression scores or not. (For comparing two means, we use t test and for more than two means, we use ANOVA F test. Actually, F test is nothing but the generalization of t-test.).
