**fields of study / plans the course is directly associated with**- there are 37 fields of study the course is directly associated with, display
**Course objectives**- The course presents principles and methods of statistical analysis, and explains what types of data are suitable for answering questions of interest.
**Learning outcomes**- After the course the students:

- are able to formulate questions of interest in terms of statistical inference (parameter estimation or hypothesis test within a suitable model);

- are able to choose a suitable model for basic types of data, choose a suitable method of inference to answer most common questions, implement the method in the statistical software R, and correctly interpret the results;

- are able to judge which questions and with what accuracy/certainty can be answered based on available data, or suggest what data should be collected in order to answer given questions with a desired level of accuracy/certainty. **Syllabus**- Basic principles of Probability.
- Random variables, their characteristics and mutual relationships.
- Properties of functions of random variables.
- Data as realisations of random variables.
- Descriptive statistics and the choice of a suitable model.
- Point and interval estimation: the framework and most common methods.
- Hypotheses testing: the framework and most common methods.
- Linear regression, Analysis of variance, Analysis of covariance.
- Methods of data collection, their purpose, scope and limitations.
- Design of experiment.

**Teaching methods**- Lectures: 2 hours a week; focused on explanation of terms, principles and methods.

Exercise sessions: 2 hours a week; focused on deeper understanding of the principles and methods, on their application to data using the statistical software R, and on interpretation of the obtained results. **Assessment methods**- During the semester: two homework assignments worth 40 points in total. After the semester: a written exam worth 60 points. The final grade depends on the sum S of the points for assignments and for the written exam. The minimum required to pass is 51 points. Score-to-grade conversion: A for S in [91,100], B for S in [81,90], C for S in [71,80], D for S in [61,70], E for S in [51,60], F for S in [0,50].
**Language of instruction**- Czech
**Follow-Up Courses****Further Comments**- The course is taught annually.

The course is taught: every week. **Teacher's information**- https://is.muni.cz/auth/el/fi/jaro2023/MB143/index.qwarp
