Sex differences on the advanced progressive matrices in college students

Sex differences on the Advanced Progressive Matrices are reported for a sample of 2222 American college students. Males obtained a significantly higher mean of 3.4 IQ points, contrary to the frequently made contention that there is no sex difference on the Progressive Matrices but confirming the position of Lynn (1994, 1999) that from the age of 16 years males obtain a higher mean on the Progressive Matrices than females. The standard deviation was a little but not significantly greater in females, contrary to the frequent assertion that the male variance for intelligence is greater than the female.
