Q69 / 100

Why is one-hot encoding commonly used for categorical features in machine learning?

Correct! Well done.

Incorrect.

The correct answer is B) It converts categories into binary indicator columns, avoiding a false sense of ordinal relationship that plain integer encoding would imply to algorithms that assume numeric ordering

B

Correct Answer

It converts categories into binary indicator columns, avoiding a false sense of ordinal relationship that plain integer encoding would imply to algorithms that assume numeric ordering

Explanation

Assigning integers like 1, 2, 3 to unordered categories implies an ordering or magnitude that does not exist. One-hot encoding creates a separate binary column per category, letting the model treat them as independent without artificial ordinal relationships.
