Results

            A between-subjects t test was conducted to determine the effect of treatment on scores. Using a two-tailed .05 criterion, we reject the null hypothesis. The experimental group (M = 10.67, SD = 2.50) scored significantly higher than the control group (M = 7.17, SD = 2.32), t(10) = 2.51, p = .031, (see Figure 1). The effect size as measured by Cohen’s d = 1.45.
