Accuracy
Why wrong: Accuracy is misleading in imbalanced datasets because a model predicting only the majority class can achieve high accuracy.
- B
Mean absolute error
Why wrong: MAE is a regression metric, not used for classification evaluation.
- C
Recall
Recall measures the proportion of actual positives correctly identified, essential for capturing minority class.

Why wrong: R-squared is a regression metric, not applicable to classification.

Precision measures the proportion of true positives among predicted positives, important for imbalanced data.
AI0-001 AI Concepts and Foundations Practice Question
This AI0-001 practice question tests your understanding of ai concepts and foundations. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
When evaluating a binary classification model, which two metrics are most appropriate for imbalanced datasets? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Recall
Recall (Option C) is correct because it measures the proportion of actual positive cases correctly identified, which is critical in imbalanced datasets where the minority class is of primary interest. Precision (Option E) is correct because it measures the accuracy of positive predictions, helping to avoid false positives when the positive class is rare. Together, recall and precision provide a balanced view of model performance on the minority class, unlike accuracy which can be misleadingly high by simply predicting the majority class.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that accuracy is always the best metric, but the trap here is that accuracy fails on imbalanced datasets, and candidates must recognize that recall and precision are the appropriate pair for evaluating minority class performance.
Detailed technical explanation
How to think about this question
In imbalanced datasets, the confusion matrix is essential: recall (true positives / (true positives + false negatives)) and precision (true positives / (true positives + false positives)) are derived from it. A real-world scenario is fraud detection, where fraudulent transactions (positive class) may be only 0.1% of data; a model with 99.9% accuracy could miss all fraud, but recall and precision directly capture detection and false alarm rates. The F1-score, the harmonic mean of precision and recall, is often used as a single metric in such cases.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
