Independent t-test Dependent/paired t-test One-way ANOVA Two-way ANOVA Repeated Measures ANOVA ANCOVA A researcher was interested in the effects of journal therapy on depression. Sixty individuals diagnosed with severe depression were randomly assigned to three different treatment groups (20 individuals in each group). The first group received journal therapy (writing about their feelings for an hour each day for three weeks) and regular counseling, the second group received only journal therapy, and the third group received only regular counseling. All sixty individuals were given a depression scale before (baseline) and after treatment. Assume the assumptions of the parametric method were satisfied. Do depression scores after the intervention differ among the three groups, controlling for or removing the effect of the baseline depression score?.

therapy, and the third group received only regular counseling. All sixty individuals were given a

method were satisfied. Do depression scores after the intervention differ among the three groups,
