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? In a standardized evaluation, five out of eight categories of reflective writing were detected automatically with substantial or almost perfect reliability, while the other three were detected with moderate reliability (Cohen's κ ranges between .53 and .85). → Thomas Daniel Ullmann 2019

q3 · i? · design · r2

Evaluation of machine learning models trained on a random 80% of labeled sentences and tested on the held-out 20%, in a standardized process applied to all eight category data sets; the article reports "Cohen’s κ ranges between .53 and .85" across categories.

"Overall, the standardized evaluation shows that five out of eight categories can be detected automatically with substantial or almost perfect reliability, while the other three categories can be detected with moderate reliability (Cohen’s κ ranges between .53 and .85)."
