Dendrogram
|

Elbow Method
|
|
Random State

None of these
|
Explanation:
Detailed explanation-1: -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).
Detailed explanation-2: -The elbow method runs k-means clustering on the dataset for a range of values for k (say from 1-10) and then for each value of k computes an average score for all clusters. By default, the distortion score is computed, the sum of square distances from each point to its assigned center.
