Ordinal factorisation is a factor analytical tool based on Formal Concept Analysis. It groups the so-called Boolean factors, given by suitable formal concepts, into well-structured families that can be interpreted as many-valued factors. In this paper we put the ordinal factorisation to work by testing it on well-documented medical data. We also compare the results with those obtained by established data reduction methods.
