MeSH Heading: Bias
Tree Number(s): N05.715.350.150; N06.850.490.500
Unique ID: D015982
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015982
Annotation: IM general only; coordinate NIM with disease /‌epidemiol, not /‌etiol; add geographic term if pertinent; do not use for "bias" as prejudice or subjectivity (= PREJUDICE or specifics)
Scope Note: Any deviation of results or inferences from the truth, or processes leading to such deviation. Bias can result from several sources: one-sided or systematic variations in measurement from the true value (systematic error); flaws in study design; deviation of inferences, interpretations, or analyses based on flawed data or data collection; etc. There is no sense of prejudice or subjectivity implied in the assessment of bias under these conditions.
Entry Term(s): Aggregation Bias; Bias, Aggregation; Bias, Ecological; Bias, Epidemiologic; Bias, Statistical; Bias, Systematic; Biases; Biases, Ecological; Biases, Statistical; Ecological Bias; Ecological Biases; Ecological Fallacies; Ecological Fallacy; Epidemiologic Biases; Experimental Bias; Fallacies, Ecological; Fallacy, Ecological; Outcome Measurement Errors; Scientific Bias; Statistical Bias; Statistical Biases; Systematic Bias; Truncation Bias; Truncation Biases
