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? Experimental-group learners showed higher final knowledge test achievement than control-group learners, with the initial test included as a covariate. → Prtljaga 2017

q2 · i? · causal · r1

Experiment with parallel groups: three experimental and three control fourth-grade classes (120 subjects after exclusions), analyzed by covariance analysis with the initial knowledge test as co-variable. Final means were E= 4.5; C= 3.2, described as "a more significant difference".

"a more significant difference was noticed on the final kno wledge test results (E= 4.5; C= 3.2), as well as an achievement decrees of the control group."
