| Abstract: | Extends both the logic and the statistical procedures used in a recent analysis by R. Rosenthal and D. B. Rubin (see record 1983-02381-001) of data on gender differences in cognitive abilities reported in a meta-analysis by J. S. Hyde (see record 1982-07673-001). The logic of a "model fitting" approach to meta-analysis is described. Relevant statistical procedures and goodness-of-fit tests are illustrated. It is concluded that sex differences are changing over time and that essentially all of the variability in the sex differences reported by different studies can be explained as a function of the publication date and the selectivity of the sampling plan used in the studies.
