ANALYSIS OF QUANTITATIVE DATA IN TWO NON-INDEPENDENT GROUPS USING STATISTICA AND SPSS SOFTWARE: PARAMETRIC AND NON-PARAMETRIC TESTS
Open article in archive
In this article we present general information about Student’s paired t-test, non-parametric Wilcoxon test for paires samples and sign test which are often used for comparing paired numerical data. Algoritms for the use of all abovementioned criteria using Statistica 10 and SPSS 20 software are presented as well as recommendations on how to interpret results of the tests. This article covers basic knowledge needed for practical implementation of tests for paired observations (continuopus data) and does not substitute reading specialized literature in biostatistics and clinical epidemiology.
