Answer Key: Linear Regression with the California Housing Dataset

1. Which features are most strongly correlated with the target variable?

Using the correlation matrix and heatmap, we find that:

• 'MedInc' (median income) has the strongest positive correlation with the target variable ('MedHouseVal').
• 'AveRooms' and 'HouseAge' have moderate correlations.
• 'AveOccup' and 'Population' are less correlated.

2. How does median income affect median house value?
