### Subject aims expressed by acquired skills and competences

The aim is -to learn students how to present a set of data by tables, graphs and descriptive measures, - to make them acquainted with some parts of probability theory, especially with the term random variable, that is one of tools for description of uncertainity of real economical situations, - to make them able to use basic types of probability distributions for solution of practical cases, - to make them know the principles of some methods of statistical inference and use them for estimating and testing population parameters, - to give the view of regression and correlation analysis.
