In hierarchical clustering, what does the term 'dendrogram' refer to?
Correct Answer: A dendrogram is a tree-like diagram that shows how clusters are arranged in hierarchical clustering.
- Step 1: Understand that hierarchical clustering is a method used to group similar items together.
- Step 2: Know that during this process, clusters are formed based on how similar the items are.
- Step 3: A dendrogram is a visual representation of these clusters.
- Step 4: Imagine a tree where each branch represents a cluster of items.
- Step 5: The height of the branches in the dendrogram shows how similar or different the clusters are.
- Step 6: The dendrogram helps us see the relationships between different clusters easily.
