Abstract
A standardization of the Progressive Matrices in Sudan for the ages 9 through 25 years is analysed for sex differences in means and variability. There are no sex differences in means at the ages 9, 11, 12, 13 and 19 years. At age 14 through 18 years females obtain higher means than males, while at ages 10 and 20-25 years males obtain higher means than females. There are no consistent sex differences in variability.
