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 i? Control groups split into weak-retrieval (Memory Index about 0.5) and strong-retrieval (about 0.6) subgroups that differed significantly and were each homogeneous internally. → P. Lopes da Cunha 2018
Evidence¶
P. Lopes da Cunha 2018¶
P. Lopes da Cunha, D. Ramirez Butavand, L. B. Chisari, F. Ballarini and H. Viola (2018). Exams at classroom have bidirectional effects on the long-term memory of an unrelated graphical task. npj Science of Learning 3:19. https://doi.org/10.1038/s41539-018-0036-7
q3 · i? · causal · r1
Post-hoc analysis of control groups found CTRw groups homogeneous (F(6,150) = 0.74, p = 0.62) and CTRs groups homogeneous (F(6,167) = 1.72, p = 0.12), but CTRw vs CTRs means differed significantly (t = 6.65, p < 0.001), so each control type was compared only with its paired EXM groups.
"When we compared CTRw vs CTRs means, we found a signi ficant difference ( p < 0.001, t = 6.65), reason why these control groups were analyzed separately and compared with their corresponding EXM groups."
