  1. Values shown are component loadings (correlation coefficients of the relationship between the components produced (B1, B2, G1 and G2) and the individual measurements). B1 represents the first unrotated component produced for the boys, B2 represents the second unrotated component produced for the boys. G1 represents the first unrotated component produced for the girls, G2 represents the second unrotated component produced for the girls. Variance is the percentage variance explained by each component. Cumulative Variance indicates the variance explained by both components together.
