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 bias in this sampling method because the researcher is only interviewing people leaving a local restaurant. This sample only includes people who have just gone out to eat, which may not be representative of the entire population in the town. People who go out to eat more frequently are likely to be overrepresented in this sample, while those who rarely eat out may be underrepresented. This could lead to an overestimation of how often people in the town go out to eat. To obtain a more accurate representation of the town's dining habits, the researcher should also consider interviewing people who have not recently eaten out.
