Abstract

Use of the chi-square statistic for investigating interspecific association has been incorrectly applied to the contact sampling method because of an invalid probability argument. The usual method of calculating expected frequencies leads to a large overestimation and hence bias towards negative association. A correct method of analysis is presented and discussed.
