Question

Quizplus · Accepted Answer

The scientist is trying to eliminate researcher bias by having a third person who is not associated with conducting the experiment score the tests. Researcher bias occurs when the researcher's own beliefs, attitudes, or expectations influence the outcome of the study. By having a third person score the tests, the scientist is reducing the likelihood of this bias. Sample bias refers to a bias in the selection of participants, control bias refers to a bias in the way the control group is implemented, and treatment bias refers to a bias in the treatment of the participants. These biases are not addressed in the scenario given.
