Cluster dendrograms of extracted terms (open-ended questions).
Cluster dendrograms are based on the Euclidean Distances’ Matrix of the 64 Salient Stems for Open-Ended Question 1, 2, 3, and 5. A Hierarchical Cluster Analysis was performed to group similar terms in relation to their TF-IDF Index. Euclidean distances are reported on a modified scale with units from 0 to 1 (0 = maximum proximity/similarity; 1 = maximum distance/dissimilarity).
