Heirarchial clusting using ____________ results in a sequence of aggregated clusters that minimizes the loss of information between the individual observation level and the cluster level​
A)McQuitty's method

C)median linkage
D)Ward's method

Quizplus · Accepted Answer

Ward's method is the best choice as it minimizes the sum of squares between the original variables and the variables estimated in the cluster. It gives well-separated clusters with minimal variance within each cluster. The other methods have some drawbacks like McQuitty's method is less reliable and has a tendency to produce long chains of singletons as clusters, centroid linkage is sensitive to outliers and can result in overly large or small clusters, and median linkage is less robust to outliers and can lead to distorted clusters.
