The Guide to the Expression of Uncertainty in Measurement (GUM) [1] is a document published by the JCGM that establishes general rules for evaluating and expressing uncertainty in measurement. [ 2 ] The GUM provides a way to express the perceived quality of the result of a measurement.
In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a quantity measured on an interval or ratio scale.. 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.
The Joint Committee for Guides in Metrology (JCGM) is a committee which created and maintains two metrology guides: Guide to the expression of uncertainty in measurement (GUM) [54] and International vocabulary of metrology – basic and general concepts and associated terms (VIM).

In daily life, measurement uncertainty is often implicit ("He is 6 feet tall" give or take a few inches), while for any serious use an explicit statement of the measurement uncertainty is necessary. The expected measurement uncertainty of many measuring instruments (scales, oscilloscopes, force gages, rulers, thermometers, etc.) is often stated ...
