**Teaching results**

The main educational goal of the course is:

• acquaint students with the principles of basic, elementary statistical methods,

• teach students to apply appropriate statistical methods in solving practical problems in the field of economic practice,

• to support students' awareness in the selection, evaluation, identification and interpretation of the results of the quantitative methods used.

Knowledge:

The successful graduate of the course will gain knowledge from the application of basic, elementary statistical methods, which can be applied in decision-making in various areas of economic practice and will use them appropriately in the study of other economic subjects, processing of theses.

Skills:

The graduate can implement, perform basic, elementary statistical analysis, construct hypotheses, solve associations between indicators, draw relevant conclusions from applied statistical procedures. The student applies the acquired theoretical knowledge to solve specific economic problems.

Competences:

After completing the course, the student is able to solve and analyze the problems of economic practice by applying appropriate statistical methods and procedures, interprets the results in a suitable way and draws conclusions based on empirical results.
