“…First, two different hierarchical cluster analyses (Ward's method, average linkage method) were employed to determine the number of clusters present in the sample. The squared Euclidean distance coefficient was selected as the similarity measure because it addressed both profile shape and elevation when assigning cluster membership (Everett, Landau, Leese, & Stahl, 2011). The final number of clusters was determined by visually inspecting the dendrogram for natural breaks in the merging of clustersa widely accepted method (Clatworthy, Buick, Hankins, Weinman, & Horne, 2005;Lange et al, 2002).…”
