Analysis of diagnostic utility

Abstract

This article was created to meet growing student demand regarding the guidelines needed to build a research tool. The following article not only shows the research process but also remind the principles for the conduct of research. The theoretical part describes only those types of ordinal scales on the basis of which an attempt has been made to create a research tool. The aim of the research is to analyse the diagnostic utility (validity) of three tools for measuring involvement. Students were asked to assess the degree of lecturer involvement. It was justified because the students are persons participating in the education process and experiencing the involvement of the lecturer concerning the way of students' education. The involvement is built on interpersonal relationships. These interpersonal relationships form a specified type of involvement ties which became the subject of analyses in the research. The research problem constitutes the question: Which of the tested tools is the most effective for conducting the research procedure concerning involvement? The answer to this question was given in the conclusion of the article. One of the tools turned out to be the most pertinent but also the best for carrying out various types of statistical analyses. It was a tool that measured the intensity of the involvement degree in percentage-wise.
