MeSH Heading: Observer Variation
Tree Number(s): E01.354.753; N02.421.450.600; N05.715.350.150.675; N06.850.490.500.250
Unique ID: D015588
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015588
Annotation: IM general only
Scope Note: The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
Entry Term(s): Bias, Observer; Inter-Observer Variability; Inter-Observer Variation; Interobserver Variability; Interobserver Variation; Intra-Observer Variability; Intra-Observer Variation; Intraobserver Variability; Intraobserver Variation; Observer Bias
