Likert scale: 1 = Strongly Disagree to 5 = Strongly Agree. [Group 1 (Traditional observation: n = 35), Group 2 (Live video streaming observation: n = 29), Group 3 (Hybrid observation: n = 31)]. H = Kruskal–Wallis test statistic. η² = Kruskal–Wallis effect size (epsilon-squared estimate). pHolm = Holm–Bonferroni adjusted p-value. Effect size classifications were based on Cohen’s (1988) criteria
