Subclaims¶
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.
q2 i? In early-twentieth-century American school surveys, pupils behind grade outnumber accelerated pupils by wide margins, e.g., 57.5 per cent behind versus 8 per cent ahead among 8942 graded pupils in Bureau county, Illinois. → J. K. W. Wallin 1911
