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? Egger's test indicates small-study effects for cognition (p = .004) and motivation (p = .002); after trim-and-fill imputation the motivation mean drops only from 0.51 to 0.43. → Michaela Arztmann 2023

q3 · i? · quant-synthesis · r3

Publication-bias analysis using Egger's regression test and Duval & Tweedie's trim-and-fill. Four studies were imputed for motivation and one for behaviour (adjusted mean 0.92); no studies were imputed for cognition. The article concludes "the basic conclusion (that games have a motivating effect compared to traditional teaching) remains unchanged".

"the observed weighted mean for motivation is 0.51 and the adjusted weighted mean, after imputing these missing studies, is 0.43"
