Course abstract

The course gives knowledge about data analysis methods, management and analysis in the different statistical software. The following topics are covered: descriptive statistics, graphical summarizing of data and qualitative data analysis methods.

Learning outcomes and their assessment

• knowledge and critical understanding about quantitative data (1st test, home work, practical works) and qualitative data analysis methods (2nd test, practical works); how to apply data analyses methods in research projects (tests, home work);
• skills to discuss the choice of methods of data processing principles, their application and implementation, to interpret the results and draw conclusions (tests, home work, practical works);
• competence to use statistical software and realize data analysis outcomes in bachelor work (the home work is developed and presented).

Requirements for awarding credit points

Laboratory works have been developed. Successfully write two tests (80%). Independent work has been developed and defended (20%). Examination.

Description of the organization and tasks of students’ independent work

Independent work: select a time series data from the Statistics website. Use a multiplicative and additive model for time series analysis. Describe the obtained results. The volume of work at least 5 pages, is uploaded to e-system, and is defended.

Criteria for Evaluating Learning Outcomes

Exam evaluation depends on the cumulative assessment of two tests (80%) and independent work (20%). Tests can be written only at specified time and once. Students who have a cumulative assessment of the study course less than 4 or wish to improve it (have at least 4) have examination. The exam includes practical part (80%) and theory (20%). The exam will be during the period of individual studies and examinations.
