To view which observations are assigned to each cluster in a k-Means model in RapidMiner, which feature should you use?

• A. Data view
• B. Cluster view
• C. Folder view
• D. Observations view

Answer: (C)

Viewing which observations belong to each cluster is best accomplished with the folder view. In RapidMiner, this view organizes results so that each cluster is represented as a folder, and opening a folder reveals all the observations assigned to that cluster. This layout makes it easy to see the exact membership for every cluster at a glance. Other views focus on raw data, per-observation details without grouping, or cluster-level summaries, so they don’t provide the clear, side-by-side view of membership that the folder view does.
