Practical examples of correlation analysis are given. Calculations of Pearson’s and Spearmen’s correlation coefficients are presented using formulas and STATA software. Main assumptions for the use of correlation analysis are discussed as well as general principles of presentation of the results in biomedical publications. The article presents only general information about correlation analysis and does not substitute special statistical literature.STATAcorrelation analysisPearson’s correlationSpearmen’s correlationSTATAкорреляционный анализкоэффициент Пирсонакоэффициент Спирмена[Гржибовский А.
