Evaluation of measurement data – Supplement 1 to the "Guide to the expression of uncertainty in measurement" – Propagation of distributions using a Monte Carlo method. JCGM 102:2011. Evaluation of measurement data – Supplement 2 to the "Guide to the expression of uncertainty in measurement" – Extension to any number of output quantities.
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). [33] The JCGM is a collaboration of eight partner organisations ...
The working group has international responsibility for maintaining and promoting the Guide to the expression of uncertainty in measurement (GUM), which is the primary document regarding measurement uncertainty. The working group has had no formal involvement in the preparation of the entry, which replaces the previous entry with the agreement ...
Tub Winner: Tru Whip. Tru Whip delivered a fine balance between flavor and texture. It's pleasantly sweet, and with a subtle hint of vanilla, its flavors aren't too overwhelming but also aren't ...

In physical experiments uncertainty analysis, or experimental uncertainty assessment, deals with assessing the uncertainty in a measurement.An experiment designed to determine an effect, demonstrate a law, or estimate the numerical value of a physical variable will be affected by errors due to instrumentation, methodology, presence of confounding effects and so on.
