Subclaims¶

q2 i? Kendall's rank correlation shows that groups ranking higher in initiating annotations also tend to rank higher in re-annotations (τ = 0.95, p < 0.05; the article prints no standardized effect size beyond the correlation statistic). → Yiqiu Zhou and Jina Kang 2026

q2 · i? · associational · r1

Group-level Kendall's tau correlation analysis (16 groups) aggregating annotation frequencies, reported under RQ2 with a printed correlation of τ = 0.95, p < 0.05. The authors describe it as indicating a "persistent engagement pattern across annotation behaviors"; no standardized effect size is printed.

"the results demonstrate a strong positive correlation between initiat- ing annotations and re-annotations (τ = 0.95, p < 0.05), indicating that students who ranked higher in initiating annotations also tended to rank higher in re-annotations."
