A meta-analysis is presented of 22 studies of sex differences in university students of means and variances on the Progressive Matrices. The results disconfirm the frequent assertion that there is no sex difference in the mean but that males have greater variability. To the contrary, the results showed that males obtained a higher mean than females by between .22d and .33d, the equivalent of 3.3 and 5.0 IQ conventional points, respectively. In the 8 studies of the SPM for which standard… Expand

Gender differences in variance and means on the Naglieri Non-verbal Ability Test: data from the Philippines.
TLDR
Results on mean score differences support the hypothesis that there are no significant gender differences in cognitive ability, and the unusual results regarding differences in variance and the male-female proportion in the tails require more complex investigations. Expand
