Using people who are readily available to the researcher may lead to a biased sample because they may not represent the population being studied. This is a form of convenience sampling and may not be representative of the larger population. A better option would be to use random sampling techniques to ensure that all members of the population have an equal chance of being selected. Using people who accept compensation or agree to participate (options A and B) may also lead to bias because these individuals may have different characteristics than those who decline to participate. Using people who have participated in other research studies (option D) may also lead to bias because they may not represent the general population.
