Abstract
Two types of models are proposed for the analysis of the measurement in nominal scale; the deterministic model and the variability model. The latter is subdivided into three types, S-P variability model (Thurstone model) where the variability is assumed between stimulus (S) and intervening psychological (P) variables, P-variability model where variability is assumed concerning P-variables and S-P: P variability model which is a combination of the former two models.
Some of the variabilities can be conceived as reliability or discriminability of the methods used. Some of the possible biases which may result from the variabilities have been analysed.
