In a preceding paper, we (Nurminen et al. 1981) advocated the use of the sole referent series as the basis of estimating moments in the construction of test statistics for comparative studies. Three simple test statistics, two metric approaches and one procedure based on ranks, incorporating this principle are introduced for small matched samples with ordinal outcome variables. Associated methods for computing an “exact” probability value are derived. The techniques are illustrated by real data from a study in the field of occupational health epidemiology.
