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 i2 Among 162 graduates of seven Rhode Island schools, intervention students enrolled at higher rates (58.0% vs 45.0%; effect size 0.32, +12) and full-time enrollment also favored the intervention (46.0% vs 32.0%; effect size 0.36, +14), but neither contrast was statistically significant. → Summer Counseling 2018
