Question

Quizplus · Accepted Answer

The scientist is trying to eliminate experimenter bias by having a third party score the tests. Experimenter bias occurs when the researcher's expectations or beliefs about the outcome of the study influence their behavior or interpretation of the results. By having someone not involved in the experiment score the tests, the scientist can reduce the potential for experimenter bias.
