6.2 Sex differences in the dark triad To test the first two hypotheses, a series of independent samples t-tests were conducted to determine if sex differences existed in mean scores for each of the Dark Triad traits and in T-scores for each of the cluster B PD subscales. With regard to the three Dark Triad traits, as hypothesized, men (M=2.79, SD=0.46) scored higher than women (M=2.60, SD=0.46) on Machiavellianism (Mach-IV), t(659)=5.33, p < 0.001 (correlation coefficient of effect size rY ?=0.203, medium effect size), and men (M=2.56, SD=0.53) also scored significantly higher than women (M=2.22, SD=0.51) on psychopathy (SRP-III), t(659)=8.41, p < 0.001 (rY ?=0.311, large effect size).
