Abstract

Statistical processing of data and visualisation of the results of analysis is an inevitable stage of working with data obtained in various fields of natural sciences, sociology, psychology or economics. In this course we will go through the basics of statistics and learn the basics of the statistical programming language R. We will teach you how to use visualisation tools (charts, graphs, etc.) flexibly to make the results of analysis as accessible and understandable as possible. You will learn how to calculate basic descriptive statistics: median and quantiles, mean and standard deviation. You will be introduced to the principles of using theoretical distributions of statistics to construct confidence intervals and test hypotheses (using the t-criterion as an example). Finally, we will discuss the difficulties encountered in multiple hypothesis testing and teach you how to overcome them.
