Which statement best describes Folder view in RapidMiner?

• A. It shows which observations belong to each cluster.
• B. It displays the cluster centroids.
• C. It lists all variables in the dataset.
• D. It shows clustering evaluation metrics.

Answer: (A)

Folder view is all about grouping results by cluster so you can see exactly which observations are assigned to each cluster. It organizes the output into folders labeled by cluster, and opening a folder reveals the observations that belong there. This direct mapping makes it easy to inspect cluster composition and understand how the data were partitioned.

Centroids, variable lists, and evaluation metrics come from other views or outputs: centroids appear in a summary of cluster characteristics, the dataset’s variables are shown in metadata or data views, and metrics show up in evaluation results rather than in the folder-organized view.
