q2 i? Regression intercepts for EA differed across SES groups even after including PGS, showing mean EA differences independent of PGS. → Eveline L. de Zeeuw 2019

q2 · i? · associational · r2

Between-family model regressing EA on PGS and sex within each SES group; intercepts differed across SES groups (Δ−2LL = 61.8, p < 0.001), indicating SES mean differences in EA beyond PGS differences.

"The intercepts differed between SES groups (Δ−2LL = 61.8, Δdf = 3, p < 0.001), showing that there were mean differences in EA across SES groups independent from differences in PGS between children."

Discussion¶

Learner Variables¶

• Socioeconomic Status — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause

• The strength of the association between polygenic score and educational achievement does not differ across SES groups — related
