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? No correlation was visible between grade level and effect sizes, or between sample size and effect sizes, suggesting the MALL effect is independent of both. → Imtiaz Hassan Taj 2016

q2 · i? · quant-synthesis · r1

Plotted comparisons of effect sizes against grade levels (Figure 1) and sample sizes (Figure 2) across the 13 studies. The article reports "no corelation visible" in either plot; no correlation coefficient is printed, so no magnitude is reported.

"there was no corelation visible between either the grade level and effect sizes (figure.1) or between the sample size and effect sizes (figure.2). it can be concluded that effect of MALL seems independent of grade level and sample size."
