Question: What is the purpose of normalization in feature engineering?

Options:

1. To increase the range of feature values
2. To ensure all features contribute equally to the distance calculations
3. To reduce the number of features
4. To eliminate outliers

Correct Answer: To ensure all features contribute equally to the distance calculations

Solution:

Normalization adjusts the scale of feature values to ensure that they contribute equally to distance calculations, which is crucial for algorithms sensitive to feature scales.
