The Kruskal–Wallis omnibus test of the question-answering motivation scales on seniority groups revealed significant differences for only Build Community Ties (χ2 = 11.57, p = 0.02). The Dunn–Bonferroni tests of post hoc pairwise comparisons indicated that graduate students had significantly higher mean ranks for the Build Community Ties scale than did full professors (see Fig 6). A similar analysis of the scales on discipline did not find significant differences.
