1 answer
Yes, there is a bias in this sampling method. By interviewing people leaving a local restaurant, the researcher is only capturing the opinions and behaviors of people who frequent that particular restaurant. This sampling method may not accurately represent the entire population of the town, as it is only targeting a specific group of individuals who are already inclined to eat out. To obtain a more accurate representation of how often people in the town go out to eat, the researcher should use a more diverse sampling method that includes individuals from various demographics and dining preferences.
