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? Posttest total time showed a significant Condition x Prior Proficiency interaction and a significant main effect of Condition, with the Assertions-Low group spending significantly less time than the Messages-Low group. → Mehak Maniktala 2020

q3 · i? · causal · r2

ANCOVA on posttest total time in the same study found a Condition x Prior Proficiency interaction (F(1,100) = 6.236, p = 0.014) and a main effect of Condition (F(1,100) = 6.913, p = 0.010); Table 2 reports means of 36.03 vs 52.94 minutes for the Low groups. No standardised effect size is printed.

"A pairwise Tukey's Honest Significant (HSD) test for multiple comparisons on the total posttest time shows a significant difference ( p = 0.008) between Assertions-Low and Messages-Low groups. The Assertions-Low group spent significantly less time on the posttest than the Messages-Low group."
