2. Individual analysis of a scientific publication - each student will search for one full text scientific publication where data analysis methods included in this course is used. After finding and reading the publication, student will give 5 to 7 minute presentation about the use of statistical methods, results and formulation of conclusions in it.
3. Independent work - each student will have to complete four tasks, including closed and open-ended questions about descriptive statistics and inferential statistics.

1. Participation in practical lectures. For each missed class, student must attend a session with another group under the current lecturer or study the topic independently and completing the test yourself questions in e-studies.
2. Oral presentation of the analysis of a scientific publication.
The grade of the course is cumulative, where:
50% – exam - independent work.
50% – multiple-choice test with 30 theoretical and practical questions in statistics with a time limit of 45 minutes.
