WebInterpretation. The within-cluster sum of squares is a measure of the variability of the observations within each cluster. In general, a cluster that has a small sum of squares is more compact than a cluster that has a large sum of squares. Clusters that have higher values exhibit greater variability of the observations within the cluster. WebMay 18, 2024 · The elbow method runs k-means clustering (kmeans number of clusters) on the dataset for a range of values of k (say 1 to 10) In the elbow method, we plot mean distance and look for the elbow point where the rate of decrease shifts. For each k, calculate the total within-cluster sum of squares (WSS).
