A truncated Ward diagram has its last merge far above the others.
What does the merge height represent?

Remember the idea
Use the inputs and evidence to recover the method. Hints and explained solutions remain collapsed; exact phrasing is not graded.
Hint 1 — Think
Recall what Ward’s vertical scale measures.
Hint 2 — Tools
Merge distance and truncated hierarchy displays.
Hint 3 — Approach
Interpret the high merge under the fitted geometry without calling it a class probability.
Explained solution
It measures the merge according to Ward geometry. It is not a class probability or proof of true groups.
It measures the merge according to Ward geometry. It is not a class probability or proof of true groups.
