Problem: The Increase in ESS by Applying Ward's Method to Four Clusters
Use Ward's method to cluster the four items whose measurements on a single variable X are given in the following table.
(a) Initially, each item is a cluster and we have the cluster
Show that ESS=0, as it must
(b) If we join cluster {1} and {2}, the new cluster {12} jas
(c) Complete the last two algamation steps and construct the dendrogram showing the value of ESS which the mergers take place.
