All three measures, i.e., single linkage, average linkage, and average group linkage, can be used to measure the similarity between clusters in hierarchical clustering. Single linkage measures the minimum distance between any two points in the two clusters being merged. Average linkage measures the average distance between all pairs of points in the two clusters being merged. Average group linkage, also known as the UPGMA (Unweighted Pair Group Method with Arithmetic Mean), measures the average distance between all pairs of points in the two clusters being merged weighted by the size of each cluster. Therefore, all three options are valid measures of similarity between clusters in hierarchical clustering.
