TEST EQUATING STUDY CONCERNING TO ALES (ACADEMIC PERSONNEL AND POSTGRADUATE EDUCATION ENTRANCE EXAM) SCORES OBTAINED AT DIFFERENT TIMES IN A YEAR

Abstract


The purpose of this to equate ALES (Academic Personnel and Postgraduate Education Entrance Exam) scores with linear equating and equipercentile equating methods in the periods of 2011 spring and autumn conducted by SPSS, to determine the most suitable one of these two methods for research and to propose the most suitable one thanks to the findings in case of a similar study. The study population was 21860 people participating in ALES made in the periods of both 2011 spring and 2011 autumn. The sample of the study was 2186 individuals, respectively selected %10 of population randomly via computer. In the study, the internal consistency was calculated without eliminating items by using KR-21 formula because data were raw scores. Analyzes were carried out because of the fact that internal consistencies were high without eliminating agents of heights. Linear and equipercentile methods applied separately to the raw scores of sizes. Error quantities were measured by WMSE formula to determine which equating method was more appropriate for research and when the data of research findings were analyzed it was found that WMSE coefficient of equipercentile method was lower. As a result of this study equipercentile equating was found more appropriate on the equating study concerning to the field of quantitative, verbal, equiponderant.
