Hypothesis tests for the difference between two population proportions using Stata

Abstract

 This educational article outlines the main methods available, using Stata statistical software, for testing hypotheses about the equality of population proportions, using sample-derived data. The article focuses on how to select the most appropriate test to use, the relevant Stata statistical software commands and the interpretation of the Stata output obtained following these commands. Both single-sample and two-sample hypothesis tests are covered.
