Claim 5:
6. The clustering device according to claim 5, wherein
when classifying the multiple element data, the batch process section is configured to:
calculate a data addition value obtained by adding element data within each cluster, and the number of element data within each cluster; and
calculate a cluster centroid for each cluster from the data addition value and the number of element data, and

the evaluation score calculation section is configured to:
acquire, for each cluster, the data addition value and the number of element data calculated by the batch process section;
calculate the second index value for each cluster using the data addition value and the number of element data which are acquired;
hold the number of element data and the second index value for each cluster; and
calculate the evaluation score or each of the evaluation scores using the second index value which is held.
