I have perfromed a Cluster Analysis using the K-means operator. I have a result. But I am not able to differentiate between the Centroid view and Folder View. Does both of them show the same reusult or are they completely different? I am posting pictures of my result.Screenshot (142).pngcentroid viewScreenshot (143).pngFoler View

    Hi @charansaireddy2 - that's a good question. The "centroid view" shows you the value of the centroid for each cluster for each attribute. For example, in the Iris tutorial data set, you get this centroid table:

    Now if you make a simple scatterplot of the data, the centroids become clear:

    (note that cluster_0 is blue/iris-virginica, cluster_1 is red/iris-setosa, cluster_2 is green/iris-versicolor).


    The "folder view" is simply a list of the id values of each element in the cluster:
