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.

q3 i2 Long naps beat the Control 1 condition (a different lecture on the same discipline) with p = 0.0246/d = 0.4119 by trial averages and a marginal nested trend (p = 0.0435/d = 0.6225). → Thiago Cabral 2018

q3 · i2 · causal · r2

Pairwise Wilcoxon Ranksum comparison (Bonferroni corrected) in the same 24-student cross-over design. The article calls the nested result a "marginal trend" despite the printed p = 0.0435 with Bonferroni-corrected alpha 0.025.

"Contents followed by long naps (>30 min) were significantly better retained than contents followed by a different lecture on the same discipline (Control 1), when assessed by trial averages ( p = 0.0246/Cohen's d = 0.4119, Fig. 1b), with a marginal trend when the data were nested per subject ( p = 0.0435/Cohen's d = 0.6225, Fig. 1c)."
