Correlation coefficients in human skulls: Significant sexual differences

This study of 500 male and female skulls proves: significant differences of correlation coefficients (p less than or equal to 0.01) occur between the two sexes. The combined variables are: 1. bizygomatic breadth (45)/skull base length (5) 2. bizygomatic breadth (45)/foramen magnum length (7) 3. bizygomatic breadth (45)/foramen magnum breadth (16) 4. bizygomatic breadth (45)/basion-bregma height (17) 5. foramen magnum breadth (16)/skull base length (5) Female skulls have generally higher correlation coefficients values than males which is interpreted as an indication of homogeneous growth.
