Questions & Step-by-Step Solutions

In hierarchical clustering, what does the dendrogram represent?
  • Step 1: Understand that hierarchical clustering is a method of grouping data points into clusters based on their similarities.
  • Step 2: Know that a dendrogram is a tree-like diagram used to illustrate the arrangement of these clusters.
  • Step 3: Realize that the dendrogram shows how clusters are formed by merging smaller clusters into larger ones.
  • Step 4: Observe that the vertical lines in the dendrogram represent the distance or dissimilarity between clusters.
  • Step 5: Conclude that the dendrogram helps visualize the relationships and hierarchy among the clusters.
