A physical therapist wants to know if low intensity aerobic exercises are effective in patients with fibromyalgia for the outcomes of pain and general health. A double-blinded randomized control trial is designed to compare a control group of patients with over the counter medication as their only treatment vs. an intervention group of low intensity aerobic exercises. Baseline, post intervention, 3months and 6 months data collection is completed using a battery of questionnaires for the variables of pain intensity (N.P.R) and general health (SF12). What is the purpose of assessing for homogeneity and confirm if the groups were similar at baseline?
