A restaurant chain 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 not to long plz
Yes, there is a bias in this sampling method. By only interviewing people leaving a local restaurant, the researcher is only getting the opinion of people who already go out to eat. This does not provide an accurate representation of the entire population in the town, as it excludes people who do not go out to eat.
