  1. Number and percentage of males and females in groups with results of Pearson’s chi-square test for frequency distribution in groups. Means (M) with standard deviations (SD) for metric variables with results of t-test (two-tailed, α = .05) for independent groups [Levene tests confirmed equal variances (p > 0.05)].
