Sex differences in general knowledge

A general information or knowledge test, which was shown to measure 19 domains of general knowledge, six first-order factors and one second-order general factor, was constructed. Data obtained from 469 female and 167 male undergraduates were tested for sex differences using Student's t and Hotelling's multivariate t. It was found that males obtained significantly higher means than females on the second-order general factor and on four of the six first-order factors identified as information about Current Affairs, Physical Health and Recreation, Arts and Science. Females obtained a significantly higher mean than males on the first-order factor identified as Family. There was no sex difference on the remaining first-order factor identified as Fashion. The results confirm the findings in a number of standardisation samples of the Wechsler tests that males obtain higher average scores than females on the Information subtests and that this is not attributable to a bias in favor of males on these tests.
