draw conclusion that rough entropy measures are correlated with standard clustering va-
lidity indices. Rough indices proved to be highly correlated with standard cluster validity
measures and cluster homogeneity measures. Rough measures are best correlated with the
β-index, next with Davies-Bouldin index and correlation with Dunn index is comparatively
the lowest. The β-index values have tendency to high correlation in all dimensions, Dunn
