The Examination of Model Fit Indexes with Different Estimation Methods under Different Sample Sizes in Confirmatory Factor Analysis*
Öz: In adjustment studies of scales and in terms of cross validity at scale development, confirmatory factor analysisis conducted. Confirmatory factor analysis, multivariate statistics, is estimated via various parameterestimation methods and utilizes several fit indexes for evaluating the model fit. In this study, model fit indexesutilized in confirmatory factor analysis are examined with different parameter estimation methods underdifferent sample sizes. For the purpose of this study, answers of 60, 100, 250, 500 and 1000 students whoattended PISA 2012 program were pulled from the answers to two dimensional “thoughts on the importance ofmathematics” dimension. Estimations were based on methods of maximum likelihood (ML), unweighted leastsquares (ULS) and generalized least squares (GLS). As a result of the study, it was found that model fitindexes were affected by the conditions, however some fit indexes were affected less than others and viceversa. In order to analyze these, some suggestions were made.

Doğrulayıcı Faktör Analizinde Farklı Örneklem Büyüklüklerinde Farklı Kestirim Yöntemleriyle Hesaplanan Uyum İndekslerinin İncelenmesi
Öz: Ölçme araçlarının uyarlama çalışmalarında ve ölçme aracı geliştirirken çapraz geçerlik çalışmaları kapsamında doğrulayıcı faktör analizi gerceklestirilmektedir. Çok değişkenli bir istatistik olan doğrulayıcı faktör analizinin hesaplanmasında kullanılan birçok parameter kestirim yöntemi ve model uyumunun degerlendirilmesinde kullanılan farklı uyum indeksleri mevcuttur. Bu çalışmada, doğrulayıcı faktör analizinde kullanılan model-veri uyum indekslerinin farklı örneklem büyüklüklerinde farklı parametre kestirim yöntemleri ile hesaplama sonuçları incelenmiştir. Bu doğrultuda PISA 2012 çalışmasına katılan ve iki boyuttan oluşan “matematiğin önemine yönelik görüşler” maddelerine cevap veren öğrenciler içerisinden 60, 100, 250, 500 ve 1000 kişilik veri setleri belirlenmiştir. Hesaplamalarda en çok olabilirlik (EÇO), ağırlıklandırılmamış en küçük kareler (AEKK), genelleştirilmiş en küçük kareler (GEEK) hesaplama yöntemleri kullanılmıştır. Araştırmanın sonucunda oluşturulan koşullardan bazı uyum indekslerinin daha fazla, bazılarının ise daha az etkilendiği belirlenmiştir. Bu doğrultuda analizler için önerilerde bulunulmuştur.
