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? After the four-phase intervention, the experimental class's mean score rose from 5.7 to 6.55, a statistically significant difference on a paired-samples t-test. → Uyen 2021

q2 · i? · causal · r1
Single-group pre-test/post-test experiment with 40 grade 8 students in Vietnam, analyzed with a paired sample t-test in SPSS 25. The article reports "a sig value of 0.000 < 0.05", so the null hypothesis of no difference was rejected; means were 5.7 (pre) and 6.55 (post).
"The significance level of 0.05 used in Table 4 led to a sig value of 0.000 < 0.05, which was found."
