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.

q3 i2 The control condition reported significantly lower perceived difficulty than the global and local support conditions, and no support reported less difficulty than global support (partial η2 = 0.10). → Steffen P. Schmidgall 2020

q3 · i2 · causal · r3

ANCOVA on perceived difficulty (extraneous cognitive load) with prior knowledge as covariate, F(3,151) = 5.29, partial η2 = 0.10. The article reports that "the control condition reported statistically significantly lower values of perceived difficulty" than global and local support, and that no support reported less difficulty than global support (SE = 0.29, p = 0.01).

"an ANCOVA with prior knowledge as covariate revealed that the experimental conditions differed statistically significantly with regard to perceived difficulty ratings, F(3,151) = 5.29, MSE = 1.61, p < 0.01, partial η2 = 0.10. Bonferroni-adjusted post-hoc multiple-comparisons showed that the control condition reported statistically significantly lower values of perceived difficulty than the global support (SE = 0.29, p < 0.001) and the local support conditions (SE = 0.29, p = 0.02)."
