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? Mean differences between human and AI feedback ranged from -.24 (favoring AI) to .83 (favoring humans), and partial eta-squared values ranged from .01 to .12. → Steiss 2023

Steiss, Jacob; Tate, Tamara; Graham, Steve; Cruz, Jazmin; Hebert, Michael; Wang, Jiali; Moon, Youngsun; Tseng, Waverly; Warschauer, Mark. (2023).

q3 · i? · causal · r2

Descriptive and ANOVA analysis of coded feedback ratings (n = 198) found "all small" partial eta-squared values from .01 to .12; ChatGPT means ranged from 3.09 to 4.02 across dimensions.

"Partial eta-squared effect sizes for variance explained by the difference in rater were all small, ranging from .01 (for criteria-based feedback) to .12 (for prioritization of essential features), indicating that the difference in raters explained very little of the differences in feedback ratings."
