Which evaluation metric is most suitable for assessing clustering performance?

Step 1: Understand that clustering is a way to group similar data points together.
Step 2: Know that we need a way to measure how well these groups (clusters) are formed.
Step 3: Learn about different metrics that can be used to evaluate clustering performance.
Step 4: Identify the Adjusted Rand Index (ARI) as one of these metrics.
Step 5: Understand that the ARI compares two different clusterings to see how similar they are.
Step 6: Realize that a higher ARI value indicates better clustering performance.
