  1. Values shown are component loadings (correlation coefficients of the relationship between the components produced (B1R, B2R, G1R and G2R) and the individual measurements). B1R represents the first rotated component produced for the boys, B2R represents the second rotated component produced for the boys. G1R represents the first rotated component produced for the girls, G2R represents the second rotated component produced for the girls. Variance is the percentage variance explained by each component. Cumulative Variance indicates the variance explained by both components together.
