Subclaims¶

q3 i2 In the whole sample MA was significantly negatively correlated with mathematics performance (rs = -.30). → Devine 2017 q3 i? Within the DD group (rs = -.09, p = .38) and the DD+RD group (rs = -.02, p = .79) the correlation was not significant. → Devine 2017 (2)

q3 · i2 · associational · r2

Spearman rank correlation in the full 1757-child sample showed "MA was significantly and negatively correlated with mathematics performance (rs = -.30, p < .001, BcaCI: -.34, -.25)", matching prior meta-analytic estimates of about r = -.30.

"In the whole sample of 1757 children, MA was significantly and negatively correlated with mathematics performance (rs = -.30, p < .001, BcaCI: -.34, -.25)."

q3 · i? · associational · r2

Within-group Spearman correlations in the DD (n = 99) and DD+RD (n = 140) subsamples were not significant; the article attributes this to the narrow range of mathematics scores in these groups, noting power of .93-.95 to detect rs = -.30.

"In contrast, the correlation between MA and mathematics performance within the DD group was not significant (rs = -.09, p = .38; n = 99; BcaCI: -.29, .12), nor was the correlation significant within the DD+RD group (rs = -.02, p = .79; n = 140; BcaCI: -.19, .14)."
