About Study Course
Objective
To get basic knowledge in data processing methods (descriptive statistics, inferential statistics to estimate differences), that can be used in bachelor's paper, analysis of scientific literature and research work in their specialty.
Preliminary Knowledge
Secondary school knowledge in Mathematics and Informatics.
Learning Outcomes
Knowledge
1.Upon completion of this course, students will demonstrate knowledge that allows to: * recognise terminology used in statistics and basic methods used in different publications; * know Excel and IBM SPSS Statstics offered data processing tools; * know data processing method criteria; * correctly interpret the most important statistical indicators.
Skills
1.Upon completion of this course, students will demonstrate skills to: * input and edit data in computer programs Excel and IBM SPSS Statistics; * prepare data for statistical analysis correctly; * choose appropriate data processing methods, incl., ability to do statistical hypothesis testing, correlation analysis; * statistically analyse research data using computer programs Excel and IBM SPSS Statistics; * create tables and graphs in Excel and IBM SPSS Statistics programs with obtained results; * correctly describe obtained research results.
Competences
1.Upon 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 Excel and IBM SPSS Statistics, practically use learned statistical basic methods to process research data.

1. Individual work with the literature – prepare to lectures accordingly to a plan.
2. Individual analysis of a scientific publication.
3. Individual work – each student will receive a research data file (or students can use their own) with previously defined research tasks. Student will statistically process data to reach defined tasks using descriptive statistic, inferential statistic and/ or analytical statistics methods. As well as to report obtained results in final paper, using defined formatting style and to present obtained results in the last lecture.
In order to evaluate the quality of the study course as a whole, the student must fill out the study course evaluation questionnaire on the Student Portal.
