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.
q2 i? The experimental group's speaking mean rose from 14.95 at pre-test to 18.30 at post-test, a statistically significant change. → Afraz 2018

q2 · i? · causal · r1
Paired-samples t-test comparing the experimental group's pre- and post-test speaking scores over six treatment sessions; the article reports a significant level of p<.001 with means of "14.95 and 18.30".
"According to the pre-test and post-test mean values of 14.95 and 18.30 as well as a significant level of p= (.000), p<.001 (table 3), the experimental group has shown a great difference at the end of the experiment."
