Main meta-analytic results. Results of analyses on a ratios of the grade means, b ratios of grade variabilities, and c coefficients of variations for girls (red) and boys (blue). Diamonds and circles represent meta-analytic estimates of mean effect sizes, and their 95% confidence intervals are drawn as whiskers. In a, natural logarithm of response ratio (lnRR) represents the average difference between girls’ and boys’ mean grades; positive values of lnRR indicate lower boys’ mean grades. In b, natural logarithm coefficient of variation ratio (lnCVR) represents the average difference in grade variation between boys and girls; negative values of lnCVR indicate greater male variance. In c, natural logarithms of the coefficient of variation (lnCVs) are shown for boys and girls to illustrate grade variation by gender; more negative values of lnCV indicate less variation.
