The second group of 17 receive the relaxation training. The subjects in each group are then given an anxiety inventory. The summarized results appear below where higher scores indicate greater anxiety. Control Group: n = 17, mean = 31, standard deviation = 6.63 Relaxation Group: n = 17, mean = 26, standard deviation = 6.20
