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.

q3 i? Class 4 (high performers) showed twin concordance of 76%, indicating familial resemblance, while struggling classes showed discordance or no statistical familial effect. → Hart 2015

Evidence

Hart 2015

Hart, Sara A.; Logan, Jessica A.R.; Thompson, Lee; Kovas, Yulia; McLoughlin, Gráinne; & Petrill, Stephen A. (2015). A latent profile analysis of math achievement, numerosity, and math anxiety in twins. Journal of Educational Psychology. https://doi.org/10.1037/edu0000045

q3 · i? · associational · r2

Affected-status agreement statistics from the twin design showed class 4 (n = 295) at 76% concordance (familial resemblance), classes 2 and 3 at 0% and 14% (individual-specific), and classes 1 and 5 at 33% and 46% with confidence intervals overlapping .50.

"For individuals in class 4, the affective status agreement statistic indicated that class membership was associated with a higher chance of both twins being assigned to the same class, in that of all individuals in the class, 76% were concordant by twin pair."
