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? Among younger students, the lowest SES quartile advances more steeply than the highest quartile (difference in m: 0.08sd, in rd: 0.15sd), but this advantage attenuates and reverses at older ages for white, black, and to a lesser extent Hispanic students, though not Asian students. → M.

Subgroup results by SES quartile (Tables 2 and 3) use an SES index from principal component analysis of a household possession index and parental education. The article states the young bottom-quartile advantage "attenuates and reverses itself at older ages for white, black, and, to a lesser extent, Hispanic students, but not for Asian ones".

"The advance for those from households in the lowest quartile of the socioeconomic status (SES) distribution is steeper than for those in the highest quartile among those tested at a younger age (difference in m: 0.08sd, in rd: 0.15sd)."
