The null hypothesis needs to be rejected in a one-way between groups ANOVA before the researcher can conduct a post hoc analysis.

A researcher reports the results of an ANOVA for a repeated-measures design as “F(2,14) = 7.85, p < .01.” This study used a sample of n = 15 participants.

The following figure reflects the results of a hypothetical study that investigated whether the combination of low-level electrical brain stimulation, transcranial direct current stimulation (tDCS), and sertraline, a commonly used SSRI antidepressant, would be effective in ameliorating depression in a group of clinically depressed individuals. The researchers randomly assigned participants to one of two medication conditions (placebo or sertraline) and to one of two brain electrical stimulation conditions (sham tDCS or active tDCS). Participants’ levels of depression was assessed using the Montgomery–Asberg Depression Rating Scale (MADRS) after six weeks of treatment.Figure: Brain Stimulation and Medication Reference: Ref 14-17 (Figure: Brain Stimulation and Medication) Based on the figure, which effects appear to be present?
