What is the measurement of uncertainty?
- Measurement uncertainty. 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.
What is estimated uncertainty?
- Estimation Uncertainty. Estimation uncertainty means the susceptibility of an accounting estimate and related disclosures to an inherent lack of precision in its measurement.
What is the uncertainty in physics?
- uncertainty principle. n. ( General Physics ) the principle that energy and time or position and momentum of a quantum mechanical system, cannot both be accurately measured simultaneously. The product of their uncertainties is always greater than or of the order of h, where h is the Planck constant.

In metrology, measurement uncertainty is a non-negative parameter characterizing the 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. ... The measurement uncertainty is often taken as the standard deviation of a state-of-knowledge probability distribution over the possible values that could be attributed to a measured quantity.
