Complete diameter
the distance represents the distance between the most remote samples belonging to the same cluster
![]()
Average diameter
the distance defines the average distance between all of the samples belonging to the same cluster

Centroid diameter
the distance reflects the double average distance between all of the samples and the cluster’s centre
