ISACA Certified Artificial Intelligence Auditor (CAIA) — Question 46

Which of the following should be an IS auditor’s GREATEST concern if class imbalance is identified in training data for an AI model?

Answer options

• A. Data drift
• B. Data quality
• C. Model bias
• D. Model overfitting

Correct answer: C

Explanation

The correct answer is C, Model bias, because class imbalance can lead to a model that favors the majority class, resulting in biased predictions. While data drift, data quality, and model overfitting are also important concerns, they do not directly stem from class imbalance in the same way that model bias does.
