What is the main advantage of using hierarchical clustering over K-means?

Correct Answer: Hierarchical clustering does not require the number of clusters to be specified in advance.

Step 1: Understand that clustering is a way to group similar items together.
Step 2: Know that K-means clustering requires you to decide how many groups (clusters) you want before starting.
Step 3: Realize that hierarchical clustering does not need you to decide the number of groups beforehand.
Step 4: Recognize that this flexibility in hierarchical clustering allows you to explore different groupings of the data.
Step 5: Conclude that the main advantage of hierarchical clustering is its ability to form clusters without needing a pre-set number.
