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.
q3 i? At the end of 11th grade, a larger fraction of ALAS students than control students were enrolled (75% vs 67%), but the difference was not statistically significant. → WWC Intervention Report: ALAS 2006
