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? Explain.
Yes, there is a bias in this sampling method. The researcher is only interviewing people who are already at a restaurant, which means they are more likely to be people who go out to eat frequently. This sampling method would not accurately represent the entire population of the town, as it would exclude people who do not go out to eat often or at all. To obtain a more accurate representation of the town’s dining habits, the researcher would need to use a different sampling method that includes a wider range of people.
