Parental occupation and mental ability
Abstract100,820 high-school seniors were given aptitude tests and listed their father's occupation. The Ohio State University psychological test, the American Council psychological examination, and the Henmon-Nelson test of mental ability were used. The authors present tables showing the distribution of scores for 6 major occupational groups and the median scores for specific occupations. The differences within the major groups are greater than the differences between groups, but the median differences between groups are statistically reliable. Groups which rank highest deviate more from the general median than groups which rank lowest.
