Question 1
A research study involves predicting house prices. Actual prices are [400,000, 600,000, 800,000], whereas predicted prices are [420,000, 590,000, 770,000]. Calculate MSE and discuss implications if the predicted prices included a significant error.
💡 Hint: Focus on using the MSE formula and analyze how the data changes your results.
Question 2
You are given two different models predicting student scores. Model A has MSE = 10, while Model B has MSE = 20. What does this suggest about the performance of both models?
💡 Hint: Think of MSE as a measure of 'error' – lower means better!
