Claims

The magnitude of sex differences in mathematics varies across geographical regions, with larger estimated effects in Central Europe (d = 0.164) and Central and South America (d = 0.153) than in North America (d = 0.047)

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q4 i? Estimated standardized mean differences were larger in Central Europe, Central and South America, and to a lesser degree North America, with geographical area a significant moderator in the full model. → Sara Caviola 2026

q4 · i? · quant-synthesis · r2

Meta-regression moderator analysis with geographical region (7 levels) entered jointly with content, grade, and GGGI; removing geographical area significantly worsened fit (χ²(7) = 19.94, p = .006). The article reports the regional estimates in the quote.

"Estimated SMDs were larger in Central Europe (d = 0.164), Central and South America ( d = 0.153), and, to a lesser degree, North America (d = 0.047)."
