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? In the read-twice condition, lessons with diagrams yielded better posttest performance than lessons without diagrams; diagram presence did not affect posttest performance in the embedded questioning or elaborative interrogation conditions. → Clinton 2016

Clinton, V., Alibali, M. W., & Nathan, M. J. (2016). Learning About Posterior Probability: Do Diagrams and Elaborative Interrogation Help? The Journal of Experimental Education, 84(3), 579-599. https://doi.org/10.1080/00220973.2015.1048847

q3 · i? · causal · r2

Mixed-effects model on posttest item accuracy in the randomized factorial experiment (N = 198). The interaction of diagram presence and questioning condition was significant, and in the read-twice condition "participants whose lessons included diagrams performed better on the posttest". No effect size printed.

"there was a significant interaction of diagram presence and questioning condition, Wald χ2(4, N = 198) = 6.89, p = .03. In the read-twice condition, participants whose lessons included diagrams performed better on the posttest than participants whose lessons did not include diagrams, B = 3.11, Wald Z = 2.29, p = .02"
