How Consistent Are Decision Studies in G Theory?
Abstract :
The aim of this research is to compare the G and Phi coefficients obtained by D studies in G theory and the actual cases for the same conditions of similar facets in D studies (when they are not randomly selected from the universe). This research is a theoretical research. The study group consists of 84 university students, 3 graduate students and 1 academician. The relevant data were gathered from the achievement test in Research Methodology Courses developed by the researchers. Edu G 6.1-e programme was used to analyze the data. According to the research findings, although G and Phi coefficients obtained by D studies and actual cases were close to each other, they differ. The findings revealed that there is no systematic relationship between G and Phi coefficients obtained by D studies and actual cases. If it is not possible to select the raters randomly from the universe, G and Phi coefficients obtained by D studies may not be the same as they are in actual cases. Therefore, researchers should be careful while interpreting G and Phi coefficients in D studies.
