What is Bias?
A one-sided viewpoint, inclination, or a partial perspective. An interviewer might inadvertently bias an interviewee’s answers by asking a “loaded” question, in which the desired response is presupposed in the question.
Bias in research can be intentional or unintentional when a systematic error is introduced into sampling or testing by choosing one result or by answering or encouraging it over others.
This can occur at any stage of the research, including study design or the process of data collection, as well as data analysis and publication. Bias leads to false conclusions and is potentially misleading. Therefore conducting biased research is immoral and unethical. Every examiner or researcher should be aware of all possible sources of bias and take every possible action to eliminate or minimize deviations from the truth.
