MATHEMATICAL AND COMPUTATIONAL ASPECTS OF TREATMENT ORDINAL MEASUREMENT RESULTS

The usage of ordinal scales for performing measurements in the area of quality engineering and applied metrology is widespread. This paper presents a way to evaluate classical metrological characteristics such as error, uncertainty and precision of single and repeated measurements based on the legitimate basic operations for ordinal data. A method for handling actions such as calibration, comparing measuring system capabilities and reproducibility evaluation, as well as comparing two or more measurement systems (MSs) referring to a known/unknown reference standard is also proposed.
