Sample Questions:

Question 1:

You are building a predictive model for customer churn using a dataset that is highly imbalanced, with a much larger number of non-churning customers than churning ones. What technique would you apply to improve model evaluation and ensure that the model is not biased by the imbalanced classes?

A) Use k-fold cross-validation to assess model performance across all data splits.

B) Use stratified sampling in your cross-validation to maintain the class distribution in each fold.

C) Use random oversampling to balance the classes before training the model.

D) Use bootstrapping to randomly sample the data and train the model on multiple iterations.

Question 2:

You are training a model using cross-validation and notice that the model’s performance metrics, such as accuracy, fluctuate significantly across different folds. What method can you apply to reduce the variance of these estimates and obtain a more reliable evaluation of your model?

A) Apply bootstrapping to generate multiple random samples of the dataset.

B) Use a larger number of folds for cross-validation (e.g., 10-fold instead of 5-fold).

C) Increase the size of the dataset by adding more features.

D) Train the model on each fold multiple times and average the results.
