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 i3 The six experimental teachers significantly differed in students' perceived support by teacher (η2 = 0.382), with two teachers scoring considerably higher (M = 4.49) and four lower (M = 3.70). → Vogelzang 2021

q3 · i3 · causal · r2

Analysis of variance on the three-item support-by-teacher scale (Cronbach's α = 0.79) used as a fidelity check among the six experimental teachers. Scheffé post-hoc analyses with p < 0.05 showed two teachers averaging 4.49 (SD = 0.58) versus 3.70 (SD = 0.89) for the four lower-scoring teachers.

"Analyses of variance with the six teachers who taught the experimental group as factor showed that the teachers significantly differed in perceived support (F(5, 189) = 22.731; p < 0.001; η2 = 0.382)."
