Group differences

How the groups asked about after a test score on each one, as Cohen's d: the difference in means in pooled standard deviation units, with a 95% interval. Positive means the group scores higher than the reference group. First attempt at each test only; correlations has the sex data as biserial r (d ≈ 2r). Sexual orientation is compared within sex, since the orientation groups differ so much in their sex ratio that a pooled comparison would mostly repeat the sex difference.
