3. Definitions of uncertainties
3.1 Measurement uncertainty
"Parameter associated with the result of a measurement, characterizing the dispersion of values that could reasonably be attributed to the measurand."
This parameter can be a standard deviation (or a multiple thereof) or the half-width of a given confidence interval. In metrological practice, this is referred to as a 95% confidence interval, with a widening coefficient of k = 2.
