Sample machine learning and bias questions
Choose the evaluation concern that each described model result raises. These examples come from the Easy setting; every generated worksheet draws a fresh set.
- A lending model is never given income, but the home neighborhood it is given tracks income very closely. What is the neighborhood acting as?
misleading overall accuracy · proxy variable
- A model learns from past hiring decisions, and those recorded decisions were themselves unfair to some applicants. Which concern is central?
misleading overall accuracy · label bias
- A payment checker lets through a payment that really was fraudulent. Which kind of error has occurred?
misleading overall accuracy · false negative

Check the sample answers
- proxy variable
A stand-in feature can carry the influence of the excluded one. - label bias
Learning from unfair recorded answers reproduces the unfairness in them. - false negative
A condition that was present went unreported. - unrepresentative training data
The examples covered a narrower population than the intended users.
Practice focus
Evaluating a model means asking who the examples represented, what the labels recorded, and which kind of mistake matters most. A single overall score can hide very different results for different groups.
Grade placement is a planning guide for choosing practice. The registry records standard-code mappings as unreviewed, so these pages are not a claim of alignment with a national standard.
