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? The experimental group's overall post-MET performance was significantly better than the control group's. → BavaHarji 2014

q3 · i? · causal · r2
In the same quasi-experimental study, the captioned group's overall post-MET performance was significantly better, "t = -6.92, p = .000", with the experimental group improving from a pre-MET mean of 67.42 to a post-MET mean of 82.88, compared to 63.10 to 68.12 for the control group.
"The t-test results confirm that the experimental group performed significantly better than the control group in the overall performance of the post-MET ( t = -6.92, p = .000)"
