Sažetak
The usual estimation of the coverage factor , using the Guide to the Expression of Uncertainty in Measurement - GUM method is based on the Central Limit Theorem and directly related to the Gaussian or t-distribution of probability of the measured value whose conditions in practice do not always have to be satisfied. The work studies especially the cases when one or several input values have a significantly higher contribution of uncertainty in relation to other input values. In such cases it is not clear whether the GUM method conditions have been met or not, which may sometimes lead to incorrect evaluation of the expanded measurement uncertainty.
