In
most medical and social studies are encountered with categorical variables. The
relationship between two or more categorical variables that summarized by
frequency and percentage is determined by tabulating. Commonly, Chi-Square
independence tests are used to examine the interdependence and interchange
between subcategories. However, the Chi-Square test gives a general result, the
subcategory(s) that make the difference are revealed by examining the
proportions differences. As the number of subcategories increases, this number
of pairwise comparisons is equal to
 and since there is 1-α confidence
in each comparison, the cumulative type I error increases as the number of
pairwise comparisons increases. The aim of this study is to using
Multinomial-Dirichlet distribution to compare the proportion differences with
fixed type I error, regardless of the number of subcategories. In application, simulation
data was obtained for the small sample (n
25), and a part of Project data that supported
by Giresun University Scientific Research Projects (SOS-BAP-A-200515-43) was
used. As a result; Multinomial-Dirichlet distribution approach has been found
to give a narrower confidence interval, especially for small sample size.

Medikal ve sosyal çalışmaların bir çoğunda
nitelik ifade eden değişkenlerle karşılaşılmaktadır. Frekans ve yüzde ile
özetlenen iki veya daha fazla nitel değişken arasındaki bağımlılık ilişkisi,
tablolaştırılarak incelenmektedir. Yaygın olarak Ki-Kare bağımsızlık
testlerinden faydalanılarak alt kategorileri arasındaki bağımlılık ve birlikte değişimi
incelenmektedir. Ancak Ki-Kare testi genel bir sonuç vermekte, farklılığı
yaratan alt kategori(ler) oran farklarının incelenmesi ile ortaya
konulmaktadır. Alt kategori sayısı arttıkça bu karşılaştırma sayısı
 kombinasyonu kadar
olmakta ve her bir karşılaştırmada 1-α kadar güven öngörüldüğünden
karşılaştırma sayısı arttıkça kümülatif olarak I. tip hata da artmaktadır. Bu
çalışmanın amacı, Multinomial-Dirichlet dağılımından yararlanarak, alt kategori
sayısına bakılmaksızın sabit I. tip hata ile oran farklarının karşılaştırmasını
yapmaktır.  Uygulamada, küçük örnek (n
25) için simülasyon verisinden ve Giresun
Üniversitesi Bilimsel Araştırma Projeleri tarafından desteklenen
SOS-BAP-A-200515-43 verilerinin bir kısmından yararlanılmıştır. Çalışma
neticisinde; Multinomial-Dirichlet dağılımı yaklaşımının özellikle küçük örnek
hacmi için daha dar güven aralığına sahip olduğu saptanmıştır.
