FURTHER EVIDENCE FOR THE EXISTENCE OF RACE AND SEX DIFFERENCES IN CRANIAL CAPACITY
Cranial capacities were calculated from the external head measurements reported for 36 samples of 7 to 15 year olds gathered by the Philadelphia Growth Center (Krogman, 1970). The core sample consisted of 169 white males, 224 black males, 135 white females, and 220 black females. After adjusting for the effects of age, stature and sex, white children averaged 1250 cm3 and black children averaged 1236 cm3. After adjusting for the effects of age, stature and race, boys averaged 1300 cm2 and girls averaged 1186 cm3.
