It only uses distances. So data normalization will not affect hierarchical clustering, but it will likely affect your distance function.

WebThe working of the AHC algorithm can be explained using the below steps: Step-1: Create each data point as a single cluster. Let's say there are N data points, so the number of clusters will also be N. Step-2: Take two closest data points or clusters and merge them to form one cluster. So, there will now be N-1 clusters.
