Which of the following statements about hierarchical clustering is true?
Group of answer choices
By horizontally "cutting" a dendrogram, one can see how to group observations into varying numbers of clusters.
For the same number of clusters and same distance measure, the clusters resulting from a k-mean approach and a hierarchical approach will be the same.
Hierarchical clustering is not affected by outliers.
Because of its nested design, hierarchical clustering will find the best set of 2 clusters, the best set of 3 clusters, etc.
