8,12,17,22,23,25,38,45,48,66,67,70,76 -> break into 3 clusters with 12, 23 and 67 as initial cluster centers

K1 = 8, 12, 17 mean: m1 = 12.33

K2 = 22, 23, 25, 38 mean: m2 = 27

K3 =45, 48, 66, 67, 70, 76 mean: m3 = 62

Re-assign:

K1 = 8, 12, 17 mean: m1 = 12.33

K2 =22, 23, 25, 38 mean : m2 = 27

K3 = 45, 48, 66, 67, 70, 76 mean : m3 = 62

Two groups are same. So, we got 3 clusters

Cluster1 = {8,12,17} Cluster2 = {22,23,25,38} Cluster3 = {45,48,66,67,70,76}
