Abstract

In analogy to quantitative measurements, the precision of qualitative measurement methods can be characterised by the repeatability standard deviation and the reproducibility standard deviation of the sensitivity. In order to determine these standard deviations, the ISO 5725-2 approach is used. A simulation study and an example demonstrate the advantages of the method.
