Question 1

What is the primary purpose of feature scaling?

To increase model size
To ensure features contribute equally
To reduce accuracy

💡 Hint: Consider why your model might get confused by vastly different scales.

Question 2

True or False: Normalization is always the preferred scaling method when applying machine learning algorithms.

True
False

💡 Hint: Reflect on the scenarios in which normalization is useful versus when standardization may be better.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a dataset with multiple features with very different scales (e.g., age, income, and height), describe how you would preprocess the dataset for a K-NN algorithm.

💡 Hint: Consider which scaling method would best suit the feature distributions.

Challenge 2 Hard

Suppose you have outliers in your data's salary feature while using a machine learning model that relies on distance metrics. How would this affect your scaling and modeling choices?

💡 Hint: Reflect on how outliers interact with different scaling methods.
