True or false: The cluster number assigned to each cluster in RapidMiner indicates the relative importance of each cluster when compared to the others.

• A. True
• B. False
• C. Cannot determine from data
• D. Both true and false

Answer: (B)

The numbers used to label clusters are just identifiers. In RapidMiner (and in clustering in general), a cluster label like 0, 1, 2 is assigned to mark membership and to reference clusters later, but it does not convey any sense of importance or significance. The ordering or the specific digits chosen for the labels are arbitrary and can be swapped without changing the actual clustering solution. If you want to compare clusters, you rely on metrics such as cluster sizes, compactness, separation, centroids, or silhouette scores—not the cluster labels themselves. So the statement is false.
