WebSep 11, 2024 · What I suspect is that people assume most of the time real data to follow the geometry of dataset 3, thus explaining the popularity of Ward's method over the others. Your assumption is probably correct, hence why Ward is used in general. Ward's method is used mostly in situations when K-means is also appropriate.
