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 i? A mixed effects model showed adding group membership significantly improved fit (AIC and BIC decreased by 23.91), while nesting by class, semester, or year did not improve fit; the condition difference remained evident. → Rosegard 2013

q3 · i? · causal · r2

Because data were collected over eight consecutive semesters, a mixed effects (hierarchical linear) model tested time and nesting. Adding group membership as a fixed effect significantly improved fit (AIC and BIC both decreased by 23.91), whereas adding class, semester, or year terms did not. The article concludes "There were no nesting effects found in the data, but the difference between conditions (arousal versus no-arousal) continued to be evident."

"The model with only group membership as a fixed effect (independent variable) significantly increased the fit indices [both Akaike and Bayesian Information Criteria (AIC and BIC) decrease by 23.91] from the base-line model where only the intercept was allowed to vary."
