Çok Boyutlu Madde Tepki Kuramının Farklı Modellerinden Çeşitli Koşullar Altında Kestirilen Parametrelerin İncelenmesi
Özet
In this study, the item and ability parameters of the data sets which have changing dimensionality features with different item numbers and sampling size were estimated with the item response theory and multidimensional item response theory; related to these estimations root mean square error (RMSE), bias, the correlation values between estimated and real parameters were examined. At the end, in order to have accurate estimations, the suggestions about the required test length and sample size were developed.
