Study course description
Preliminary Knowledge:
Secondary school background in mathematics and informatics.
Objective:
To get basic knowledge and skills in data processing methods (descriptive statistics, methods of inferential statistics to estimate differences between groups and relationships between variables), to use in scientific work.

Assessment
Unaided Work:
1. Individual work with the literature – preparation to lectures according to the plan. 2. Individual analysis of scientific publication. 3. Individual work in pairs – every pair will get a research data file (or students can use their own) with previously defined research tasks. Students will analyse data to reach requirements of defined tasks using descriptive statistics and inferential statistics, show obtained results in a scientifically appropriate way and present them in the last lecture.
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. At the end of the course is a graded exam that consists of two parts, where: 50% – practical task with a database, 50% – multiple-choice test with 30 theoretical and practical questions in statistics.
Final Examination (Full-Time):Exam (Written)
Final Examination (Part-Time):
Learning Outcomes
Knowledge:After completion of this course, the student will demonstrate basic knowledge that allows to: * recognise terminology used in statistics and basic methods used in different publications; * know commonly used data processing tools in MS Excel and IBM SPSS; * know data processing criteria of various statistical methods; * interpret correctly the most important statistical indicators.
Skills:After completion of this course, the student will demonstrate skills to: * input and edit data in computer programs MS Excel and IBM SPSS; * prepare data for statistical analysis correctly; * choose appropriate data processing methods, incl., will be able to do statistical hypothesis testing; * statistically analyse research data using computer programs MS Excel and IBM SPSS; * create tables and graphs in MS Excel and IBM SPSS programmes with obtained results; * describe obtained research results correclty.
Competencies:After completion of this course, students will be able to argument and make decisions about statistical data processing methods, use them to achieve research aims, using computer programs MS Excel and IBM SPSS, practically use learned statistical basic methods to process research data.
