| Course abstract | |
| Students acquire experimental design and experimental data processing methods, as well statistical methods assumptions. During the studies the real examples related to agriculture and livestock are using. Statistical software is provides for problem tasks solving. Students will use data analysis methods in research projects and bachelor work. | |
| Learning outcomes and their assessment | |
| After completing the course student will have: knowledge and critical understanding about experimental design and data analysis methods; apply appropriate experimental design and statistical analysis techniques in students research projects (the practical works are developed, assessment tests are successfully written, successfully passed the theory exam);
skills to define test hypothesis; to choose according to the research project test hypothesis and data analysis method; to interpret results; to formulate conclusions (the practical works are developed, assessment tests are successfully written, home works are developed); competences in collaboration with supervisor to realize research in bachelor work; to use data analysis methods in research projects and bachelor work (assessment tests are successfully written, home works are developed and defended). |

| Requirements for awarding credit points | |
| Examination. Examination include a practical tasks on the course subjects and a theoretical subjects acquired during the study course and. All practical works and two tests should be executed. Two home works has been developed and public defended. | |
| Description of the organization and tasks of students’ independent work | |
| The organization of independent work during the semester is independently studying literature, using academic staff member consultations. Home works has been developed and public defended. Home work: to formulate the aim and three tasks, test the hypotheses using at least 3 statistical methods, based on the data of the master thesis. | |
| Criteria for Evaluating Learning Outcomes | |
| Exam evaluation depends of the semester cumulative assessment: 1st test – 40%, 2nd test – 40% and home work – 20%. Students who have a cumulative assessment of the study course less than 4 or wish to improve it (at least 4) hold the complex exam during the session. The exam includes practical part (60%) and theory (40%). | |
