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.

q2 i? Across 21 four-way ANOVAs of individual-learner WD values with task difficulty, specificity, content, and complexity as predictors, task complexity and task difficulty explain the majority of the variance, with some effect of task specificity. → Sweet 2012

q2 · i? · causal · r2

Factorial ANOVA of the individual-learner WD variant across 21 four-way ANOVAs (one per learner type, 84 design cells) suggests "task complexity and task difficulty explain the majority of the variance in the WD statistic" with some effect of task specificity.

"These ANOVA results suggest that task complexity and task difficulty explain the majority of the variance in the WD statistic with some effect of task specificity as well."
