Toksilojik ve İlaç geliştirme çalışmalarında maruz kalınan hastalığı iyileştirmede kullanılacak en küçük etkili doz düzeyi bulunmak istenir. Sınır olarak alınan sıfır kontrol dozunu (placebo kontrol) aşan ilk doz düzeyi en küçük etkili doz düzeyi olarak adlandırılır. En küçük etkili doz düzeyi varyans analizinde ortalamalar arasında fark yoktur hipotezi reddedilmesinden sonra yapılan çoklu karşılaştırma testleri ile belirlenmektedir. Bu çalışmada en küçük etkili doz düzeyinin belirlenmesi için kullanılan İkili ve Helmert karşılaştırmaları ele alınıp bu yöntemlerin parametrik ve parametrik olmayan uyarlamaları karşılaştırılmıştır.

In development studies of toxicological and medicine, minimum effective dose (MED) which deal with any illness, is wanted to be found. The first dose exceeds the zero control dose (or placebo control dose) which can be taken a boundary value, is called MED. The MED is detected by multiple comparsions after the null hypothessis which is “there is no differance between the means.”, is rejected in ANOVA. In this study pairwise and Helmert comparsions which is used for detecting MED are studied. For this comparisions parametric and non-parametric step-down closed analysis methods are compared according to their empirical significance levels.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
