Abstract

Uncertainties in measurement will lead to certain risks of incorrect decisions, such as accepting a bad product. With the rise in interest in human perception, not only in sectors such as health care, services and safety, where the human factor is obvious, but also from manufacturers of all kinds interested in customer perception, there is a need to handle uncertainties in qualitative observations. This lecture reviews how this can be tackled with a measurement system analysis approach, particularly where Man acts as a measurement instrument. Connecting decision risks when handling qualitative observations with perceptive choice, information theory, and generalized linear modelling – through the Rasch invariant measure approach – enables a proper treatment of ordinal data and a clear separation of person and item attribute estimates. This leads in turn to opportunities of establishing measurement references, and the metrological quality assurance that is urgently needed in many contemporary applications.
