Subclaims¶

q3 i? EduYears GPS explained 7.6% of the variance in GCSE scores, 6.6% in family SES, 5.2% in achievement and 2.1% in ability; the article prints no standardised effect size for these correlations. → Smith-Woolley 2018

q3 · i? · associational · r3

Correlational analysis of EduYears GPS with selection factors and GCSE in the TEDS sample, reported in Supplementary Table S3. Only variance-explained percentages are printed, with no standardised effect size; the 7.6% GCSE figure is described as 'similar to previous analysis of these data'.

"EduYears GPS was positively correlated with each of the selection factors (see Supplementary Table S3), explaining 2.1% of the variance in ability, 5.2% in achievement and 6.6% in family SES. EduYears GPS was also positively correlated with GCSE, explaining 7.6% of the variance in GCSE scores"

Discussion¶

Related Claims¶

• After controlling for selection factors and EduYears GPS, genetic differences between school types disappear and school type explains less than 1% of GCSE variance (down from 7%) — related
• Students in state non-selective schools have lower EduYears polygenic scores than students in grammar (d = 0.41) and private (d = 0.37) schools, with no significant difference between grammar and private schools — related
