Sex differences in achievement self-attributions: An effect-size analysis

An effect-size analysis of the findings on sex differences in the use of achievement self-attributions was performed to determine if there were relationships between these two variables that accounted for more than 5% of the variance. The effect-size index used was an estimate of omega squared (²). Two kinds of sex difference effects were examined: (a) the main effect for sex and (b) the simple sex difference effects for success and failure, respectively. With the exception of luck attributions for success, whose ² was .01, all ²s were less than .01. It was concluded that the studies surveyed provided no evidence of the existence of consequential relationships between sex, achievement, and self-attributions.
