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.
Dendrogram – A dendrogram is a tree-like diagram that illustrates the arrangement of clusters formed through hierarchical clustering, showing how clusters are merged or split.
Hierarchical Clustering – A method of cluster analysis that seeks to build a hierarchy of clusters, often represented visually by a dendrogram.
