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? Students guided by staff tutors received somewhat higher course marks than students guided by peer tutors; the difference was statistically significant but small in practical terms. → Schmidt 1995

q3 · i? · causal · r2

Field experiment aggregating achievement data at the tutorial-group level across 98 problem-based health sciences courses; ANOVA showed a small significant advantage for staff tutoring, with average scores of 6.79 versus 6.64 on a ten-point scale, "statistically significant, F(1,733) -- 9.42, p < 0.002".

"The effect of staff versus peer tutoring was small - average score in the staff tutoring condition: 6.79; peer tutoring: 6.64. This difference, however, is statistically significant, F(1,733) -- 9.42, p < 0.002."
