What is the main purpose of using the silhouette coefficient in clustering?

Step 1: Understand that clustering is a way to group similar items together.
Step 2: Know that we want to see how well these groups (clusters) are formed.
Step 3: Learn that the silhouette coefficient is a number that helps us measure the quality of these clusters.
Step 4: Realize that the silhouette coefficient looks at two things: how close items in the same cluster are to each other (compactness) and how far apart different clusters are from each other (separation).
Step 5: Understand that a higher silhouette coefficient means better-defined clusters, while a lower one indicates that the clusters may not be well-formed.
