Which of the following is not a procedure to check the quality of clustering results?
A)Perform cluster analysis on the same data using different distance measures.Compare the results across measures to determine the stability of the solutions.
B)Delete variables randomly.Perform clustering based on the reduced set of variables.Compare the results with those obtained by clustering based on the entire set of variables.
C)Use the same method of clustering and compare the results.
D)Split the data randomly into halves.Perform clustering separately on each half.Compare cluster centroids across the two subsamples.

Option C suggests using the same method of clustering and comparing the results. This is not a procedure for checking the quality of clustering results, but rather a step in the clustering process itself. A procedure to check the quality of clustering results should involve comparing different aspects of the clustering results using different techniques, as suggested in the other three options. Therefore, option C is the one that is not a procedure for checking the quality of clustering results.
