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? The mean difference in deficits between primary and secondary students is δ = −0.01 and not statistically significant (P = 0.556); the authors state they cannot be certain deficits differ between levels. → Bastian A. Betthäuser 2023

Evidence

Bastian A. Betthäuser 2023

Bastian A. Betthäuser, Anders M. Bach-Mortensen & Per Engzell. (2023). A systematic review and meta-analysis of the evidence on learning during the COVID-19 pandemic. Nature Human Behaviour. https://doi.org/10.1038/s41562-022-01506-4

q3 · i? · quant-synthesis · r3

Bivariate comparison by level of education (Fig. 6b; medians primary −0.12, secondary −0.12) using common-effects models with study-clustered standard errors. The null difference is underpowered, as the authors explicitly note; equivalence was not tested.

"Our analysis yields no evidence of variation in learning deficits across grade levels (mean difference δ = −0.01, t(41) = −0.59, two-tailed P = 0.556, 95% CI −0.06 to 0.03). Due to the limited number of available estimates of learning deficits, we cannot be certain about whether learning deficits differ between primary and secondary students or not."
