Unbiased
Unbiased (/ʌnˈbaɪəst/), derived from the prefix 'un-' meaning 'not' and the adjective 'biased' meaning 'unfairly prejudiced for or against someone or something', is a term used in various fields including Statistics, Medicine, and Psychology. It refers to the absence of bias, which is a tendency to lean in a certain direction, either in favor of or against a particular thing.
In Medicine
In the field of Medicine, 'unbiased' often refers to an impartial viewpoint, free from any preconceived notions or prejudices. This is particularly important in the context of Clinical Trials, where an unbiased approach ensures that the results are not influenced by the researchers' personal beliefs or expectations.
In Statistics
In Statistics, an unbiased estimator is one whose expected value is equal to the parameter it is estimating. This means that over many iterations of the experiment, the average outcome of the estimator should be close to the parameter.
In Psychology
In Psychology, being unbiased refers to the ability to make fair and objective judgments, free from personal feelings or influences. This is crucial in areas such as Cognitive Psychology and Social Psychology, where researchers must ensure their personal beliefs do not influence their observations and interpretations.
