AI0-001 AI Concepts and Foundations Practice Question
A hospital uses an AI system to prioritize patient triage based on vital signs and medical history. During a trial, the system consistently assigns lower urgency to elderly patients with chronic conditions, even when their symptoms suggest high risk. Which approach best addresses this bias?
⚠ Common exam trap
CompTIA often tests the misconception that changing the model architecture (e.g., switching to a decision tree) or manually tweaking feature weights can fix bias, when the real solution lies in auditing and rebalancing the training data.
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
✓
Audit the training data for representation of elderly patients and retrain with balanced data
The bias originates from the training data underrepresenting elderly patients with chronic conditions, causing the model to learn skewed urgency patterns. Auditing the data for representation and retraining with balanced data directly addresses the root cause by ensuring the model learns from a fair distribution of cases, which is a standard bias mitigation technique in AI systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a different dataset from a similar hospital without checking demographics
Why it's wrong here
Using a different dataset without validation may perpetuate or introduce new biases.
- ✗
Manually increase the weight of age-related features in the model
Why it's wrong here
Manual weighting can introduce new biases and lacks systematic validation.
- ✗
Replace the neural network with a decision tree to simplify decision logic
Why it's wrong here
Model simplification does not guarantee fairness and may reduce performance.
- ✓
Audit the training data for representation of elderly patients and retrain with balanced data
Why this is correct
Auditing the training data for representation of elderly patients directly addresses the dataset bias causing the system to deprioritise this group. Retraining with balanced data corrects the skewed distribution of chronic-condition cases, satisfying the fairness constraint that the AI must not systematically discriminate based on age. This approach ensures the model learns genuine risk patterns rather than spurious correlations from under-represented subgroups.
