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? Score suggestions alone and clusters alone each cut average grading time by 69%; the combination of clustering with score suggestions gave the largest reduction, 73%. → Rebecka Weegar · Peter Idestam-Almquist 2024 q2 i? Reviewing a correctly scored answer took far less time (0.27-0.35 seconds on average) than grading an answer without support (about 8.8-10.3 seconds). → Rebecka Weegar · Peter Idestam-Almquist 2024

q2 · i? · causal · r1

Timed grading during a retake exam, with question groups A-D receiving different combinations of clustering and score suggestions (Table 2). Group D combined both supports; groups A (score suggestions) and B (clusters) each showed a 69% reduction. The average time spent reviewing a correctly scored answer was 0.31-0.35 seconds across groups.

"Combining clustering with score suggestions gave the largest reduction in average time spent on grading an answer: 73%. The time saved was compared group-wise, i.e. to the average time spent on grading answers in the same group without the support of machine learning."
