Everyday final applications of measurement processes are mostly aimed at making a decision, on the basis of comparison between the measurement result and a threshold, which could be a single numerical value or another measurement result. Of course, the latter case is the more general one since the single-value threshold is, from a metrological point of view, a measurement result with zero associated uncertainty or, more specifically, a measurement result whose associated uncertainty is much lower or negligible, with respect to the uncertainty associated to the other measurement result....
