Comparison of Quantitative Data in Two Paired Samples Using Stata Software

Abstract

In this paper we have presented basic principles of analysis of quantitative data in two paired samples. Examples of normality testing, calculating paired t-test both manually and using the STATA software have been given. We have also considered assumptions for using paired t-test as well as the main principles of presentation of the results in scientific publications. The article has given only basic information on the use of t-test in research and it does not substitute reading specialized literature.
