quantity value representing a measurement result

NOTE 1 For a measurement involving replicate indications, each indication can be used to provide a corresponding measured quantity value. This set of individual measured quantity values can be used to calculate a resulting measured quantity value, such as an average or median, usually with a decreased associated measurement uncertainty.

NOTE 2 When the range of the true quantity values believed to represent the measurand is small compared with the measurement uncertainty, a measured quantity value can be considered to be an estimate of an essentially unique true quantity value and is often an average or median of individual measured quantity values obtained through replicate measurements.

NOTE 3 In the case where the range of the true quantity values believed to represent the measurand is not small compared with the measurement uncertainty, a measured quantity value is often an estimate of an average or median of the set of true quantity values.

NOTE 4 In the GUM, the terms “result of measurement” and “estimate of the value of the measurand” or just “estimate of the measurand” are used for 'measured quantity value'.

ANNOTATION (informative) [9 December 2016] The term "measured value" can be used instead of the full term "measured quantity value" only if there is no possibility for ambiguity or misinterpretation in the particular context. In particular, the term "measured value" is sometimes used for indication, and this is not what is meant by "measured quantity value".
