ANALYSIS OF QUANTITATIVE DATA IN TWO INDEPENDENT SAMPLES USING STATISTICA AND SPSS SOFTWARE: PARAMETRIC AND NON-PARAMETRIC TESTS
This is the second paper of the series of articles where we present basic principles of statistical data analysis using Statistica and SPSS software for beginners. Step-be-step algorithms for Student’s unpaired t-test and Mann-Whitney test for independent samples are presented. The main aim of this paper is to provide basic knowledge on ho to compare continuous variables in two independent samples with practical examples using commonly used software. The article complements, but does not substitute specialized literature on biostatistics and clinical epidemiology.
