Your teacher will grade your response to ensure you receive proper credit for your answer. 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 leaving a local restaurant, which means they are already more likely to be people who go out to eat often. This sample may not accurately represent the entire population of the town, as it may not capture the views of people who do not go out to eat frequently. To reduce bias, the researcher should also consider interviewing people who do not go out to eat often, perhaps by surveying a random sample of the town's residents.
