AI0-001 AI Concepts and Foundations Practice Question
A data scientist is training a supervised learning model for customer churn prediction. Which TWO types of bias are most likely to affect the model's fairness and accuracy if not addressed?
⚠ Common exam trap
CompTIA often tests the distinction between data-level biases (selection, measurement) and human cognitive biases (confirmation bias), so candidates mistakenly pick confirmation bias because it sounds plausible in a data science context.
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
✓
Selection bias
Selection bias (B) occurs when the training data does not represent the true customer population, e.g., using only data from a specific time period or region, leading to a model that fails to generalize. Measurement bias (C) arises from systematic errors in how features are recorded, such as inconsistent data collection methods across customer segments, which can skew predictions and harm fairness.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Algorithmic bias
Why it's wrong here
Algorithmic bias is a consequence of biased data or design, not a type of data bias.
- ✓
Selection bias
Why this is correct
Selection bias arises when the sample is not representative of the population, leading to skewed predictions.
- ✓
Measurement bias
Why this is correct
Measurement bias occurs when data collection methods systematically misrepresent true values.
- ✗
Sampling bias
Why it's wrong here
Sampling bias is a subset of selection bias; the question expects distinct types.
- ✗
Confirmation bias
Why it's wrong here
Confirmation bias is a human tendency, not a data bias.
