NOTE 1 A measurement result generally contains “relevant information” about the set of quantity values, such that some may be more representative of the measurand than others. This may be expressed in the form of a probability density function (PDF).

NOTE 2 A measurement result is generally expressed as a single measured quantity value and a measurement uncertainty. If the measurement uncertainty is considered to be negligible for some purpose, the measurement result may be expressed as a single measured quantity value. In many fields, this is the common way of expressing a measurement result.

NOTE 3 In the traditional literature and in the previous edition of the VIM, measurement result was defined as a value attributed to a measurand and explained to mean an indication, or an uncorrected result, or a corrected result, according to the context.

ANNOTATION (informative) [5 June 2014] Here "quantity value" can be replaced with "value" without ambiguity: "set of values being attributed to a measurand together with any other available relevant information."

ANNOTATION (informative) [5 June 2014] This definition differs from the definition in the second edition of the VIM (VIM2) ("value attributed to a measurand, obtained by measurement") in recognition of 3.1.2 in the GUM ("In general, the result of a measurement is only an approximation or estimate of the value of the measurand and thus is complete only when accompanied by a statement of the uncertainty of that estimate.")
