Subclaims¶

q3 i? Across 48 studies, the estimated mean FSIQ gender difference slightly favours males but is practically negligible (d = 0.09, equivalent to 1.395 IQ points). → D. Giofrè · K. Allen · E. Toffalini · S. Caviola 2022 q3 i? When only newer WISC versions (III/IV/V) are considered, the FSIQ difference drops to d = 0.05 and is statistically non-significant. → D. Giofrè · K. Allen · E.

q3 · i? · quant-synthesis · r3

Multilevel random-effects meta-analysis of 48 studies (78 samples) reporting WISC FSIQ by gender. The pooled effect was "significant but practically negligible, with slightly higher scores in males than in females"; standardization-sample-only estimates were virtually the same (d = 0.10).

"The estimated mean effect size was significant but practically negligible, with slightly higher scores in males than in females, d = 0.09, 95%CI [0.04, 0.14], p < 0.001."

Discussion¶

Related Claims¶

• Gender differences in fluid intelligence (gF) on the WISC are negligible, and newer fluid-reasoning subtests show no difference or favour females — related
• Gender differences on WISC subtests and factors are generally smaller or unchanged with newer WISC versions, never larger — related
• Females outperform males on WISC processing speed (gS) with a medium advantage (d = -0.37), larger for Coding than Symbol search — related
