Statistical Methods in Medical Research

The textbook Statistical Methods in Medical Research was developed in response to the growing need for a systematic and modern approach to statistical methods in medical research. Its primary purpose is to provide students of medical faculties, as well as researchers in the field of medicine, with a clearly structured and practically oriented introduction to statistical methodology necessary for understanding, analyzing, and interpreting data in medical sciences. Starting from the requirements of contemporary medical practice, the authors aimed to make this textbook a reliable guide for the application of statistical methods. For this reason, particular emphasis is placed on the practical application of methods, while theoretical concepts are presented in a simple and clear manner and in the context of solving real research problems. The content of the textbook covers the most important areas of statistics relevant to medicine: descriptive statistics, probability theory and theoretical distributions, sampling, estimation of population parameters, parametric and nonparametric statistical tests, as well as correlation analysis. The text also includes statistical tables necessary for practical work, enabling readers to directly apply the presented methods. A special feature of the textbook is the chapter dedicated to the application of statistical software SPSS and R. This chapter demonstrates how statistical problems arising in medical practice can be solved using these statistical software tools, thereby establishing a connection between theory, practice, and computer technology.
