Suppose that a data set has been partitioned into two clusters, C1 and C2, with centroids c1 = (4, 9) and c2 = (8, 5), respectively. Clusters C1 has been assigned the points p1 = (5, 3) %3D p2 = (5, 4) р3 3 (10, 7) and cluster C2 the points p4 = (2, 4) p5 = (5, 8) %3D Calculate the within-cluster variation of the given partitioning.
