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? The experimental group using the AVDS tool achieved considerably higher test scores than the control group, with more than 75% of students scoring 80-100 belonging to the AVDS group. → Kogan 2024

q3 · i? · causal · r2
Randomised experiment: 78 students randomly assigned to experimental (n=39, using the AVDS tool during the test) and control (n=39, without it) groups, on a six-question AVL-tree performance test. The article reports "a significant difference existed in the test scores" with no printed effect size.
"A significant difference existed in the test scores of the experimental and control groups (see Fig. 5). For the experimental group, the test scores were considerably higher: more than 75% of students who got grades from 80 to 100 belonged to the group that used the AVDS tool."
