q2 · i? · associational · r1

Grading-bias analysis of peer assessment data from the online class, comparing ratings of same-country versus other-country submissions. The paper reports own-country work was rated "3.6 % higher than those from elsewhere"; no standardized effect size is printed.

"Students also rated peers’ work from their own country 3.6 % higher than those from elsewhere."
