AWS Certified AI Practitioner (AIF-C01) — Question 64

A company has installed a security camera. The company uses an ML model to evaluate the security camera footage for potential thefts. The company has discovered that the model disproportionately flags people who are members of a specific ethnic group.
Which type of bias is affecting the model output?

Answer options

• A. Measurement bias
• B. Sampling bias
• C. Observer bias
• D. Confirmation bias

Correct answer: B

Explanation

The correct answer is B, as sampling bias occurs when the data used to train the model is not representative of the entire population, leading to skewed results. The other options, such as measurement bias and observer bias, refer to different types of inaccuracies in data collection or interpretation, while confirmation bias involves favoring information that confirms pre-existing beliefs.
