The following is the output of the cluster centers I got from a cluster model (kmeans - 6 clusters)
3.371069, 3.920354, 3.629747, 3.700000, 3.988506, 3.740385
However, after segmenting the data into the 6 clusters and taking the average of the data for each of the 6 clusters, I get a different set of numbers than the above.
3.7, 3.6, 3.6, 3.8, 4.2, 3.3
My question is are cluster centers different than means?
Why am I getting different values?

They are the same.
When you run K-Means, the cluster center changes every iteration. In each iteration, cluster center or mean is given for that specific cluster. In the next iteration, a new cluster may be formed. The cluster centers need to be calculated again.
When the algorithm converges, you get the absolute means of the clusters formed. For most intents and purposes, they are the same.
