    Answer:

      biased

    Step-by-step explanation:

    Any time a selection criterion is used that is other than a random draw, the selection is biased.

    For a medical study, the bias may be intentional. The study may have the purpose of determining treatment efficacy based on age, gender, or previous medical history.
