Measure uncertainty
http://www.columbia.edu/~sn2294/pub/jln.pdf WebMeasurement Uncertainty Every measurement contains uncertainty. It isn’t possible to measure a “true” value using any analytical method in existence. Therefore, assessment of uncertainty is vital because it can strongly affect interpretation of data and decisions regarding suitability of the method for the data to be gathered.

WebMeasurement uncertainty (MU) is a parameter that characterizes the dispersion of possible values around a laboratory result. Just as a patient’s history and clinical presentation are critical to interpreting results, MU should also be considered. In an ideal world, all sources of variation around lab results would be identified and eliminated.

In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the standard deviation. By international agreement, this uncertainty has a probabilistic basis and reflects incomplete knowledge of the quantity value. It is a non-negative … WebApr 7, 2024 · The History of Statistics: The Measurement of Uncertainty before 1900 - Kindle edition by M. Stigler, Stephen .
