The use of graph theory in the implementation of psychodiagnostic projects on the example of researching the leadership qualities of participants in software development teams

Abstract

The article proposes consider the application of visual analysis of psychological testing results through the use of directed graph representations. It is proposed to consider the method of visual analysis by means of various representations based on the analysis of the number of connections between the elements of the system, considered as the basis for the formation of a directed graph. In the example considered in the article, it is proposed to consider the scales of the integrated test technique used as the vertices of the graph. As the main views, the application of calculating centrality properties based on the number of links, the topological structure of links, and the Page Rank parameter is demonstrated. It is proposed to use the method of visual analysis of the graph as an additional to the classical method of correlation analysis used in processing the results of the application of psychodiagnostic methods. The possibility of using visual analysis to form hypotheses about the possible optimization of the structure of the scales used in the design of psychodiagnostic techniques (test batteries) is shown. In parallel, the results of the analysis of the leadership qualities of such a category of specialists as software developers (members of development teams) are presented.
