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? · causal · r1
Independent samples t-test comparing the two authentic-video groups (combined) with the control group on the researcher-made posttest. The authentic-video groups "outperformed the control group", t(48) = 3.553, p = .001; no effect size is printed.
"the experimental group (combination of group 1 and 2) ( M = 20.44, SD = 3.097) outperformed the control group ( M = 17.40, SD = 2.778), t (48) = 3.553, p = .001"
