Question
Single linkage is a measure of calculating dissimilarity between clusters by:
a.
computing the average dissimilarity between every pair of observations between the two clusters.
b.
considering only the two closest observations in the two clusters.
c.
considering the distance between the cluster centroids.
d.
considering only the two most dissimilar observations in the two clusters.
a.
computing the average dissimilarity between every pair of observations between the two clusters.
b.
considering only the two closest observations in the two clusters.
c.
considering the distance between the cluster centroids.
d.
considering only the two most dissimilar observations in the two clusters.
Explanation / Answer
The correct answer is option b.
Single linkage clustering is one of the simplest hierarchical clustering method. It is also known as neighbor technique where the distance between the groups is defined as the distance between the closest pair of objects where only pairs consisting of one object from each group are considered.
