q2 · i? · associational · r1

Mean rank aggregation of complete four-item rankings from the end-of-term survey, reported separately by cohort and combined. The human-recorded personalized condition was hypothetical (never produced); the article notes this ordering "was stable across course offerings".

"In the Spring cohort, human-recorded personalized videos had a mean rank of 1.44, followed by AI-generated personalized videos (2.31), human-recorded non-personalized videos (2.69), and AI-generated non-personalized videos (3.56). The Fall cohort showed a nearly identical pattern (1.57, 2.21, 2.69, and 3.52, respectively)."
