What is wrong with the following statement: “In our study, people with bipolar disorder who underwent therapy in addition to taking medication were significantly less likely (p < 0.05) to require hospitalization as compared to those taking medication alone. We found no significant differences in the effect of adding therapy for men and women suffering from bipolar disorder. Thus, we conclude that men and women benefit equally from adding therapy to treatment with medication"
A.Finding no significant differences between men and women does not justify concluding that the effects on men and women are the same.
B.It is incorrect to conclude that adding therapy to treatment is effective unless you also have a condition testing the effects of therapy only.
C.Hospitalization is not a valid measure for assessing the effectiveness of psychiatric treatment.
D.Reporting a statistically significant difference does not tell us enough about the sample differences to draw a conclusion.
Therapy might be the whole deal. Perhaps the medication had no effect at all. We do not know based on these results.
