Requirements to the exam -
Last update: Mgr. Michal Štefánek (29.04.2022)
Written test, testing theoretical knowledge (8 open questions - 4 points each). At least 50% points are required to pass the exam. The exam can be entered only after passing of the practicals.

Practicals consist of analysing datasets by introduced statistical methods. This is achieved in the form of three tests (to be elaborated partly at home and partly during lessons of practicals). At least 65% of points must be obtained from these tests in total. More information on Moodle subject.
 
 
Alternatives under CoViD 19 measures
The tests at praciticals and exam shall be transferred into Moodle environment. Other conditions remain the same.
