Challenge Problems

Push your limits with challenges.

Question 1

You have a dataset containing categorical variable 'Education' with values 'High School', 'Bachelor', and 'Master'. Discuss how you would apply label encoding here and explain the reasoning behind your approach.

💡 Hint: Consider the implications of the educational levels on future processes.

Question 2

Suppose you're given a dataset with a nominal variable 'Color' that includes 'Red', 'Blue', and 'Green'. What would be the challenges of applying label encoding here, and how could that affect your model?

💡 Hint: Think about how categories relate (or don’t relate) to each other.
