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? The researcher-developed 25-item multiple-choice BTAT had a reliability coefficient of 0.84 using KR-21 as reported in the methodology section. → Gambari 2014
