Thematik

The aim of the course is to introduce students to the fundamental concepts of data management and statistics used in biological and biomedical research, and to provide practical skills for using modern tools required for data analysis. During the course, students will become familiar with proper data structuring, basic statistical thinking, the principles of hypothesis testing, and the key aspects of experimental design. The training places particular emphasis on the problem of multiple comparisons, the interpretation of statistical power and effect size, as well as the specific challenges associated with the analysis of omics data. Through practical examples, students will learn data management in Excel and RStudio environments, and within the framework of a small project they will develop an analysis plan related to their own research question.

The course aims to develop critical statistical thinking and to support students in independently and soundly interpreting, analyzing, and presenting their research data.
