Quizplus · Accepted Answer

The sequential threshold method is a nonhierarchical method where a cluster center is selected, and all objects within a pre-specified threshold value from the center are grouped together. The Ward's procedure is a hierarchical method based on minimizing the within-cluster variance, and the optimizing partitioning method is a nonhierarchical method that seeks to find the optimal number of clusters by maximizing the distance between them. The parallel threshold method is not a commonly used clustering method. Therefore, the best choice is C.
