  1. A

    'SquareFootage' is a feature

  2. B

  4. D

    'Price' is a feature

  5. E

    'Price' is the label

Show answer and explanation

Correct answers: A, B, C, E

Explanation

In supervised machine learning, features are the input variables used to make predictions, while the label is the target variable we aim to predict. In this dataset, 'SquareFootage', 'NumberOfBedrooms', and 'Neighborhood' are the features providing input data, and 'Price' is the label that the model will predict.

  • A. Correct.

    'SquareFootage' is a feature because it is an input variable used to help predict the target value.

  • B. Correct.

    'NumberOfBedrooms' is a feature because it is an input variable that contributes information to the model.

  • C. Correct.

    'Neighborhood' is a feature because it is another input variable providing contextual data for the model.

  • D. Incorrect.

    'Price' is not a feature, as it represents the target value we are trying to predict.

  • E. Correct.

    'Price' is the label because it is the output variable (target) the model is trained to predict.
