An example of a biased question is, "It's OK to smoke around other people as long as they don't mind, right?" or "Is your favorite color red?" A question that favors a particular response is an example of a biased question.
Biased questions favor one answer compared to another and may make certain assumptions that lead the respondent in a particular direction without considering other alternatives. They may also contain extraneous information which may influence the respondent one way or another.
Other examples of biased questions include "Do you think it is okay to have an abortion if the mother's health is endangered?" and "Would you prefer to eat a delicious steak or a plain peanut butter sandwich?"
