Determinants of success of an education system can be the facilities offered during an educational process and the qualifications obtained afterwards. However, conversion of the offered facilities into outputs efficiently in the performance evaluation plays an important role for an educational system. On the contrary, comparison of Turkish university performances can be generally performed according to only output based performance indicators like academician performances and nationwide exam results of their graduates publicly. Aim of this study is to calculate the relative efficiencies of 18 statistics departments in Turkey, which are considered as decision making units, using data envelopment analysis. Reasons for inefficiencies of departments arise from pure technical efficiency component. Furthermore, a second stage analysis is implemented to observe the effects of external factors called non-discretionary inputs on efficiency results. Finally, efficiency differences between two types of departments are tested according to their education programs with a Mann - Whiney U Test.

TÜRKİYE’DEKİ İSTATİSTİK BÖLÜMLERİNİN GÖRELİ ETKİNLİKLERİNİN VERİ ZARFLAMA ANALİZİ ILE ÖLÇÜLMESİ

Bir eğitim sisteminin başarısındaki belirleyici faktörler: eğitim süreci içinde sunulan olanaklar ve eğitim süreci sonrası elde edilen yeterlilikler olabilmektedir. Bununla birlikte, eğitim sistemlerinin performanslarının değerlendirilmesinde sunulan olanakların çıktılara etkin bir şekilde dönüştürülmesi önemli bir rol oynamaktadır. Buna karşılık olarak Türkiye’deki üniversite performanslarının karşılaştırılmaları genellikle akademisyen performansları ve ülke genelinde yapılan ortak sınav sonuçları gibi performans belirleyicileri üzerinden sadece çıktı yönlü olarak yapıldığı gözlemlenmektedir. Bu çalışmanın amacı karar verme birimi olarak ele alınan Türkiye’deki üniversitelerde eğitim veren 18 adet istatistik bölümünün göreli etkinliklerinin veri zarflama analizi yardımı ile hesaplanmasıdır. Bölümlerin toplam etkin olamamaları teknik etkinsizliklerinden kaynaklandığı sonucuna ulaşılmıştır. Ayrıca, kontrol edilemeyen girdiler olarak adlandırılan dış etkenlerin etkinlik skorları üzerindeki etkileri bir ikinci aşama analizi kullanılarak araştırılmıştır. Son olarak ise iki farklı tipte eğitim veren istatistik bölümlerinin etkinlik skorları arasındaki farkın istatistiksel anlamlılığı Mann-Whitney U testi ile sınanmıştır.
