Subclaims¶
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? In two intact classes of female second-grade high school EFL students in Birjand, Iran (n = 55, convenience sample), the class taught listening via 21st century skills scored significantly higher on a national listening post-test than the class taught traditionally (p = 0.021). → Ashraf 2017

q2 · i? · causal · r1
Independent samples t-test on listening post-test scores of 55 female second-grade high school students in two intact classes in Birjand, Iran (convenience sampling; the methods give 25 experimental and 30 control, the abstract the reverse) after 12 sessions by the same teacher; the article reports "p-value = 0.021 < α = 0.05". Descriptives: control mean 10.70, experimental mean 12.25. One study in one school and population; it does not establish the effect for EFL instruction generally.
"results of the t-test indicated that there was a significant difference between the mean scores of the control and experimental groups in post-test because: p-value = 0.021 < α = 0.05."
