### Course abstract

The aim of the course is to provide students with a theoretical understanding of the basic concepts of probability theory and mathematical statistics with demonstrations of practical application of theory. The main emphasis is on the principles of practical research, professional evaluation and interpretation of intermediate and final results of calculations. In this course, a lot of attention is paid to probability distributions and their characteristics, random variables in engineering.

### Learning outcomes and their assessment

Knowledge - able to demonstrate basic and specialized knowledge specific to the field of mathematics and a critical understanding of this knowledge; able to demonstrate understanding of probability distributions and their characteristics, random variables in engineering sciences; (laboratory work)
Skills - using the acquired theoretical knowledge and skills, can formulate and analytically describe information, problems and solutions in the field of mathematical statistics, explain and reasonably discuss these topics with both specialists and non-specialists and use the freely available R program for data processing (laboratory works).
Competencies - able to independently obtain, select and analyze information and use it, make decisions and solve problems in mathematical statistics; able to conduct practical research, analyze the intermediate result, professionally evaluate and interpret the final result.
