Ordinal Analysis - Crossed Orderings


Data Form: Between-subjects / between-groups / independent observations

Data Type
: One quantitative outcome ordering (variable), and at least one categorical grouping ordering

Hypotheses
: Ordinal (e.g., Group1 < Group2;  Group1 < Group2 < Group3 on the outcome ordering)

Traditional analogs
: Independent samples t-test, between-subjects ANOVA, Mann-Whitney U test

Summary: This analysis can be used when you wish to compare two or more groups of persons on a quantitative ordering (variable). For instance, males and females can be compared with regard to their height (a continuous quantity), or Catholics and Protestants can be compared with regard to their number of daily prayers (a discrete, countable quantity). Three or more groups can be compared as well. This analysis can therefore be used instead of an independent samples t-test or a oneway ANOVA. With regard to classic non-parametric statistical tests, this analysis is most similar to the Mann-Whitney U test for independent samples.
