Answer:
Single linkage is a measure of calculating dissimilarity between clusters by
b. considering only the two most similar observations in the two clusters.
Explanation:
Single Linkage:
It is a type of hierarchical clustering which is used to measure the dissimilarity between clusters by considering the only two observations that are closest in the clusters.
- So, according to above point the option b is correct.
- The option a is not correct as we don't consider the distance between the cluster centroids.
- The option c is not correct as computing the average dissimilarity between every pair of observations between the two clusters is not done rather we consider the two closest similar observations in the cluster so that's why the option d is also incorrect.
