Step 1:Randomly assign means
m1=3, m2=4
Step 2:Calculate the distance of the objects from the mean and assign the objects to the cluster with minimum distance
k1={2,3} k2={4,10,12,20,30,11,25}
Step 3:Reassing means
m1=(2+3/2) m2=(4+10+12+20+30+11+25/2)
m1=2.5, m2=16
Step 4:Calculate distance and assign clusters
k1={2,3,4} k2={10,12,20,30,11,25}
Step 5: Reassing means
m1=3,m2=18
Step 6: Calculate distance and assign clusters
k1={2,3,4,10} k2={12,20,30,11,25}
Step 7: Reassing means
m1=4.75 , m2=19.6
Step 8:Calculate distance and assign clusters
k1={2,3,4,10,11,12} k2={20,30,25}
Step 9:Reassing means
m1=7 , m2=25
Step 10:Calculate distance and assign clusters
**k1={2,3,4,10,11,12} k2={20,30,25}**
Repeat the steps till you get same clusters
As clusters in step 8 and step 10 are same ,these are the final clusters.
