The curvilinear relationship between masculinity (x-axis) and adiposity (y-axis) explained more variance (F = 24.038, p < 0.0005, R 2 = 0.351) than the curvilinear relationship between adiposity (x-axis) and masculinity (y-axis) (F = 18.934, p < 0.0005, R 2 = 0.301), although both were highly significant.
