  • Nonresponse Bias

    Bias that occurs when the people who were unable to be reached or unwilling to participate in a sample have substantially different opinions than the people who were included in the sample, resulting in a misrepresentation of the population.

  • Participation Bias

    Bias that occurs when participation in a study is voluntary. People who feel strongly may be the only participants.
