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.

q4 i? The variation in effect sizes across the 53 studies was substantial and not due to chance, motivating moderator analyses. → Dahl-Leonard 2024

Evidence

Dahl-Leonard, K., Hall, C., & Peacott, D. (2024). A meta-analysis of technology-delivered literacy instruction for elementary students. Education Tech Research Dev (2024) 72:1507–1538. https://doi.org/10.1007/s11423-024-10354-0

q4 · i? · quant-synthesis · r2

Heterogeneity analysis within the same meta-analysis of 53 studies. The article reports "Q = 165.38, I2 = 68.56, df = 52, p < .001", indicating substantial true heterogeneity; no effect size is printed for this finding.

"The Q statistic indicated that the effect sizes were heterogeneous and the I 2 statistic indicated that the substantial variation in the effect sizes of this set of studies was not due to chance (Q = 165.38, I2 = 68.56, df = 52, p < .001)."
