Summary

A sample of 170 Regina school children, divided into subgroups according to family size and socio-economic status, was tested on the Otis Beta Mental Ability Test. The results demonstrated the existence of a definite relationship between intelligence and socio-economic status, but no significant relationship between family size and IQ, except among low socio economic status males. These results, interpreted as reflecting the changing relationship between intelligence and family size, are possibly the outcome of a changing fertility pattern within the various socio-economic status groups.
