knownmeasured
Knownmeasured is a term used in metrology and data reporting to describe a quantitative value that has been obtained by direct measurement with a calibrated instrument, accompanied by a documented measurement uncertainty and traceability to a standards framework. The term signals that both the numeric result and its uncertainty are known and specified, rather than estimated or inferred.
Characteristics of knownmeasured data include a measured value, an associated standard uncertainty or confidence interval, documentation
Origins and scope: The phrase is used in laboratory practice and data-processing workflows to distinguish measured
Applications: Knownmeasured values appear in experimental reports, calibration certificates, quality assurance records, and process-control data where
Examples: A temperature reading of 23.56 °C with a standard uncertainty of 0.05 °C, traceable to ITS-90;
