Expanded Uncertainty
The expanded uncertainty is obtained by multiplying “Standard Combined Uncertainty” by a “Coverage Factor” (Usually 2 in the context of the normal distribution; to equal approximately 95.5% of probability). The Expanded Uncertainty enables us to obtain an uncertainty measurement that will determine the interval or range, in which the true value of a measurement (the measurand) is believed to lie with a high level of confidence.
