Question

A restaurant chain’s owners are trying to decide if they want to open up a franchise in your town. To help them decide, they want to find out how often people in your town go out to eat. A researcher interviews people leaving a local restaurant. Is there a bias in this sampling method? Expla

Answer 1

Yes, there is a bias in this sampling method. By only interviewing people leaving a local restaurant, the researcher is only capturing a specific subset of the population - those who eat out at restaurants. This may not accurately represent the entire population of the town, as there are likely people who do not eat out at restaurants regularly or at all. This sampling method may skew the results and not provide a comprehensive understanding of how often people in the town go out to eat.
