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 experiment group's attention span scores increased significantly after the brain teaser curriculum (pre-test mean 24.79, post-test mean 35.35, t=-12.98, p<.05). → Altun 2016

q3 · i? · causal · r1

Dependent samples t-test on the experiment group (n=113) in a pre-test/post-test controlled study of six-year-olds at Merkez Kindergarten. The mean rose from "𝐗̅pre=24.79" to "𝐗̅post=35.35" with t=-12.98, p<.05; no effect size is printed.

"the mean pre -test score was found as 𝐗̅pre=24.79, while the mean post -test score was found as 𝐗̅post=35.35. It was seen that the t value obtained in regards to the difference between mean scores (t= -12.98) was significant on level of .05 (p<.05)"
