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? Difficulty ratings were higher for scenario 2 than scenario 1, a significant difference. → Anders Bouwer 2010

Anders Bouwer, Bert Bredeweg. (2010). Graphical means for inspecting qualitative models of system behaviour. Instr Sci 38:173–208. https://doi.org/10.1007/s11251-008-9083-4
q2 · i? · design · r2
Post-scenario difficulty ratings (1 = easy to 5 = difficult) in the 30-participant evaluation: scenario 2 mean "M = 3.07" versus scenario 1 "M = 2.53", t(29) = -2.64, p = 0.013. No effect size is printed.
"The participants rated the questions in scenario 2 ( M = 3.07) as more difficult than scenario 1 ( M = 2.53) ( t(29) =- 2.64, p = 0.013)."
