Challenge Problems
Push your limits with challenges.
Question 1
You are comparing two models predicting housing prices. Model A has an RMSE of $3,000, while Model B has an RMSE of $1,500. Discuss the implications of these figures and which model you would choose.
💡 Hint: Consider not just RMSE, but the overall context of the dataset and operational implications.
