Abstract

The purpose of this article is to bring to the attention of the educational research community several cautions regarding the use of inferential statistics for single proportions, differences between proportions, and quotients of proportions. The user of such procedures is urged to pay particular attention to the selection of the appropriate formula for the standard error and to the assumption of the independence of the observations.
