Question

Quizplus · Accepted Answer

Researcher bias refers to the experimenter's personal expectations or beliefs that can affect the research outcomes or their interpretation. This bias can result in the unintentional influencing of participants or selectively reporting certain results. Experimental blinds are methods used to reduce the influence of researcher bias, but they do not refer to the bias itself. Sample bias refers to a bias that arises from the selection process of participants, and treatment bias refers to a bias that may arise due to the treatment or intervention given to participants.
