Which statement regarding biased sampling is false?
1) Online sampling is biased because only the people who happen to visit the website will take the survey.
2) A radio call-in survey is biased because only people who feel strongly about the topic will respond.
3) A survey handed to every third person leaving a library is biased because everyone leaving the library was not asked to participate.
4) Asking for experts to take a survey is biased because they may have particular knowledge of the topic.
Answer (2)
The answer is number four.
The false statement regarding biased sampling is number four, which claims that asking experts to partake in a survey is biased due to their knowledge. In contrast, expert opinions can provide valuable insights and are not necessarily unrepresentative of general population views. The other options accurately describe types of bias found in sampling methods.
