Abstract

The former approach is extended to determine the overall uncertainty by combining the uncertainties of the individual results of n measurements where the difference in the individual results is statistically significant. The difference, defined as an unrecognized uncertainty arising from a random effect, is considered as an additional uncertainty. Now, it is possible to determine the overall uncertainty by combining the uncertainties of the individual results whether the individual results are statistically different or not.
