Özet:

 


This study aims to use k-means cluster analysis to improve the standard setting process, to determine the passing score in two samples by three methods, to examine the validity of the cluster analysis results using an external criteria, and to compare the cluster analysis results with those produced by Angoff, Yes/No, and Ebel test centered methods. In this study, the main sample consisted of 305 students and the validation sample consisted of 179 students. The data set is composed of the students' responses to a 20-item achievement test. On the other hand, the number of judges determining the passing score according to the test centered standard setting methods was 17. A moderate correlation was found between the external criteria and the results of cluster analysis for the validation sample. Medium and highly significant relationships were observed between the different statistical methods for determining the passing score. According to the study results, in order to achieve the highest relationship with the test centered standard setting methods’ results, the following methods could be proposed respectively: determine the passing score based on the range comprising the lowest score of the first cluster and the highest score of the second cluster; logistic regression and the average score of successful cluster.
