Study course description
Preliminary Knowledge:
Knowledge of mathematics and informatics relevant to the programme of secondary education.
Objective:
To acquire basic knowledge and skills in statistical data processing methods (descriptive statistics, methods of inferential statistics to estimate differences between groups and relationships between variables) required for the development of research work and the application of statistical indicators in their specialty.

Assessment
Unaided Work:
1. Individual work with literature – preparation for each class according to the thematic plan. 2. Individual analysis of a scientific publication. 3. Independent work in pairs: each pair will get a research data file (or students can use their own) with previously defined research tasks. Students will process the data to fulfil requirements of the defined tasks using descriptive statistics and inferential statistics, describe the obtained results in a scientifically appropriate way in the final paper and present the results during the last class. A. After successfully accomplishing this course, please fill out the study course evaluation form to give us feedback, we will appreciate that a lot!
Assessment Criteria:
For successful integration of knowledge and to prepare for the final exam, the student performs the following activities (mandatory, not graded): 1. Participation in practical lectures. A practical assignment for each missed class. 2. Oral presentation of the analysis of a scientific publication. 3. Oral presentation of independent work. The grade of the course is cumulative, where: 50% – test with 30 practical tasks using datasets, 50% – exam (multiple-choice test with 30 theoretical and practical questions in statistics).
Final Examination (Full-Time):Exam (Written)
Final Examination (Part-Time):
Learning Outcomes
Knowledge:Upon completion of this course, students will have acquired knowledge that will allow to: * recognise terminology used in statistics and basic methods used in different types of publications; * be competent in commonly used data processing tools in MS Excel and IBM SPSS; * be aware of data processing criteria for various statistical methods; * interpret the most important statistical indicators accurately.
Skills:Upon completion of this course, students will be able to: * enter and edit data in the computer programs MS Excel and IBM SPSS; * correctly prepare data for statistical processing and analysis; * choose appropriate data processing methods, including the ability to do statistical hypothesis tests; * statistically process research data using the computer programs MS Excel and IBM SPSS; * create tables and graphs in MS Excel and IBM SPSS programs for the obtained results; * describe the obtained research results correctly.
Competencies:Upon completion of this course, students will be able to take an informed decision about the use of statistical data processing methods to achieve research aims, using the computer programs MS Excel and IBM SPSS; to use the acquired basic statistical methods in processing research data.
