The concept of a measurand

It is understood that the result of the measurement including all required corrections is the best estimate of the value of the measurand.

However, since the measurand cannot be completely specified without an infinite amount of information, the result of a measurement is only an approximation or estimate of the value of the measurand.

It means: All possible outcomes of a measurement are subjected to a probability distribution .

Thus the estimate of the value of the measurand is complete only when it is accompanied by a statement of the uncertainty of that estimate .
