Which university departments have a more favorable view of Wikipedia usage?
Executive Summary: This is an analysis of a Likery survey on university faculty perceptions and practices of using Wikipedia as a teaching resource. In particular, departments will be clustered by how favorably they view Wikipedia usage according to 5 Likert scale questions. Categorical Principal Component Analysis was used to aggregate the questions, and then a Kruskal Wallis test and Dunn post hoc test were on the first principal component to cluster the departments. Two groups are distinguished from each other: Sciences, Engineering & Architecture and Arts & Humanities view Wikipedia more favorably than Health Sciences and Law & Politics.
