Abstract
Biologists frequently use nondirectional heterogeneity tests when comp aring three or more populations because a suitable directional test is unavailable or is not practical to implement. Here we describe a test , the ordered heterogeneity test, that permits testing against simply ordered alternative hypotheses in the context of almost any nondirecti onal test. The test has a wide range of parametric and nonparametric a pplications. Graphs are developed for calculating exact P values.
