Conventional Sex Differences in Personality: Does Sex or Verbal Ability Level Account for More Variance?
Subjects were 106 students categorized into four groups on the basis of their sex and verbal ability: very bright men ( n = 23), very bright women ( n = 30), below average men ( n = 23) and below average women ( n = 30). Scores were also obtained from five scales of the California Psychological Inventory and the Attitudes Toward Women Scale. Six, 2(sex) × 2(ability levels) fixed effects factorial analyses of variance were computed yielding 12 F ratios. Estimates of ω2 were also computed for each significant F ratio. Four ω2 estimates of .02 to .11 were obtained for the independent variable of sex whereas five ω2 of .03 to .26 were obtained for the independent variable of ability level. In that four of the values of ω2 for ability were greater than any for the variable of sex, it was concluded that verbal ability better accounts for more variance in the personality-attitude measures used than does sex of subjects.
