Bu çal ışmada, grup içi korelasyon katsay ı s ı n ı n örnekleme da ğı l ı m ı n ı n belirlenmesi amaçlanm ışt ı r. Bunun için, simülasyon tekni'ğ inden yararlan ı larak, 100 000 simülasyon denemesi sonunda, çeş itli grup aras ı korelasyon yap ı s ı ndaki populasyonlardan rasgele al ı nan değ i ş ik grup say ı s ı ve örnek geniş liğ indeki örneklerde hesaplanan grup içi korelasyon katsay ı lar ı n ı n dağı l ı mlar ı elde edilmi ştir. Sonuç olarak, grup içi korelasyon katsay ı s ı nin normal da ğı lmad ığı belirlenmiştir.

The Sampling Distribution of Infra-Class Correlation Coefficient

Öz

The determination of the sampling distribution of intra-class correlation coefficient was purposed in this study. For this, the simulation technique was used. The intra-class correlation coefficients were calculated at the end of the one hundred thousand simulation experiments and then the shape of the distribution of these values was looked. These distributions were obtained the samples taken randomly from the populations, which have the various inter-class correlation structures and the different number of groups and sample sizes. Consequently, it was seen that the intraclass correlation coefficient was non-normal distributed.
