A kind of sample entropy is used as a measure of segregation between two groups of animals. This index is used to perform a test of segregation under the supposition of samples coming from multinomial independent distributions. For a large sample test the asymptotic distribution is found. This test is asymptotically equivalent to the classical χ 2 for contingency tables. The exact test is developed in a less general situation.
