Abstract

Counting by weighing is a rapid procedure for obtaining N items (e.g., seeds) based on weight rather than exact Counting. We show how to modify the test statistic used for comparing m population proportions (e.g., seed germination rates) when independent samples are taken using this approximate counting procedure. The modified test will have approximate size a as advertised under the null hypothesis that there is no difference among the in proportions. A simulation study is conducted to determine the small to moderate sample size Type I error rates of the classical and modified tests. (C) 2008 Elsevier B.V. All rights reserved.
