In the context of a survey conducted on a defined population of all blue-eyed people, the example of selection bias would be:
A. Excluding brown-eyed people from the selection process of the survey
Explanation:
1. In this scenario, by excluding brown-eyed people from the selection process, the survey results would only represent a portion of the defined population (blue-eyed people) and may not provide a comprehensive or accurate picture of the entire group.
2. This exclusion introduces bias as it limits the diversity within the surveyed group, potentially leading to skewed or incomplete findings.
3. To ensure unbiased results and a representative sample of the defined population, it is essential to include all relevant subgroups (in this case, both blue-eyed and brown-eyed individuals) in the survey selection process.
