### Course abstract

Students acquire understanding of statistical methods importance to make accurate judgments and logical conclusions in the scientific work processes. Students acquire skills to use mathematical statistics methods for statistical hypothesis testing to compare means, as well as testing hypothesis with correlation and regression analysis.

### Learning outcomes and their assessment

Knowledge – to understand the importance of mathematical statistics in sociology, covering traditional methods but with greater emphasis on its practical application for surveys of social processes (laboratory works). Skills – to use appropriate mathematical statistical methods of data analysis, interpret numerical information and results of statistical analyses, use computer statistical packages and interpret the outputs (laboratory works, tests). Competence – to analyse and present data analysis results of social research by using statistical analysis outcome (independent work).

### Course Content(Calendar)

1. Application of mathematical methods in social sciences.
2. Basics of probability theory.
3. Probability distributions. Normal distribution law.
4. Population and sample data. Evaluation of population parameters.
5. Statistical hypotheses. Classification of statistical tests.
6. Hypothesis for comparing data distributions.
7. 1st test.
8. t-test for dependent samples.
9. Non-parametric statistical methods for dependent samples.
10. t-test for independent samples.
11. Non-parametric statistical methods for independent samples.
12. Hypotheses about comparing relative frequencies.
13. Analysis of variance.
14. Testing hypotheses in correlation and regression analysis.
15. Chi-squared test.
16. 2nd test.

### Requirements for awarding credit points

2 tests during the course;
representation of independent work results.

### Description of the organization and tasks of students’ independent work

During the semester student has to perform independent work, which provides analysis of social survey data. The work must be written and submitted electronically on the e-learning site. Presentation of the work should be given to the audience.

### Criteria for Evaluating Learning Outcomes

Cumulative course grade will be determined during the semester by the relative weights given:
independent work – 20%;
test Nr. 1 – 40%;
test Nr. 2 – 40%.
