What can be one reason for bias in data?

Answer and explanation

Correct answer: Overrepresentation of a single group

If one group is overrepresented while other groups are underrepresented, the data may not represent the full population fairly. An analysis or model based on such data may produce results that favour the overrepresented group. Balanced representation, diverse sources, and regular checks can help reduce this risk.
