Multivariate sex differences and similarities estimated from projected distances in the raw and PCP datasets. A and E Scaled density function for the males (blue) and females’ (red) distributions of the projected distances’ scores in the raw and PCP datasets. Within each panel, the percent of overlap (O) as well as the probabilities of superiority for males and females (PS) as well as the p-value associated and an R² effect size index derived from the comparison of these PS values using Cliff’s delta are provided. C and D Scatterplots of the bivariate relationships (quantified by a robust analog of the correlation coefficient Pearson’s r) between the projected distances and TIV scores in the raw and PCP datasets. E and F Scatterplots of the bivariate relationships (quantified by a robust analog of the correlation coefficient Pearson’s r) between the projected distances and Pclass scores in the raw and PCP datasets (M = males, F = females)
