Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design an experiment to test the impact of varying K on cluster quality in a dataset with known distributions. Explain your methodology.

💡 Hint: Consider how to measure 'closeness' among clusters.

Challenge 2 Hard

Analyze a real-world dataset (e.g., customer data) where specifying K was challenging. What approach did you take?

💡 Hint: Think about tools you could use to assess the quality of different clusters.
