Initially, the problems of research preparation are considered, where a number of basic methodological concepts are introduced, such as types and objects of research, methods of sample selection, classification of variables and relations between them, data types, measurement problems, types of control research, and others. Then, three basic groups of research models are processed, which are frequency, factorial and correlation plans. Within each of the three groups, the models are gradually presented from simple to more complex types. Subsequently, the basic forms of processing, analysis and interpretation of results are presented, especially for all three groups of drafts. The advanced part where students are trained to collect, analyze and process data with multivariate procedures that are in line with the trends of the world's leading journals in the field (in depth research). These are procedures of exploratory and confirmatory factor analysis, cluster analysis, and Structural Modeling Methods. The emphasis is on the logic and above all the practices mentioned above. At the end of the course, the standard structure of the written research report is described.
