Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

In a study analyzing prediction errors for different models, you find that increasing data complexity leads to variations in RMSE. Explain why this happens.

💡 Hint: Link model complexity to overfitting or underfitting tendencies.
