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.

Answer 1

Yes, there is bias in this sampling method. The researcher is only interviewing people leaving a local restaurant, which means that the sample is limited to only those individuals who eat out at restaurants. This may not be representative of the entire population in the town, as there may be individuals who don't eat out at restaurants for various reasons. As a result, the data collected may not accurately reflect how often people in the town go out to eat.
