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 i3 The two sequencing groups differed significantly only in reference book use, with PS-DI opening and reading the procedure document more frequently. → Sabrina Ludwig 2026

q3 · i3 · causal · r2

Log file analysis of mouse clicks and keystrokes during the problem-solving scenario, deriving behavioural indicators such as note-taking and document reading. Reference book use showed "d = .83" (M = 4.51 for PS-DI vs 1.3 for DI-PS); bi-gram sequence analysis yielded no additional significance.

"They only significantly differ in their activities regarding reference books that contain a document showing the procedure of supplier selection (MDI-PS = 1.3; SDDI-PS = 2.89 and MPS-DI = 4.51; SDPS-DI = 4.67, d = .83)."
