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? For the 20–30-year age group, two-way ANOVA found no statistically significant effect on retention at any of the four time intervals. → Nader Haghani & Samira Kiani 2018

q3 · i? · causal · r1

Two-way ANOVA for the 20–30-year age group (CG n = 15, EC n = 21); the article reports "F (1, 34) = .80, p = .379" for short-term retention and non-significant results at all other intervals. No effect size printed.

"The F-value for short-term retention is statistically insignificant (F (1, 34) = .80, p = .379). This also applies to the medium-term retention (F (1, 34) = 1.44, p = .239)"
