The hypothesis test for the equality of two population means of independent groups is the most commonly used statistical analysis with applications in medical sciences, agriculture, biology, engineering, social sciences and so on. This paper presents the RSStest package created to perform hypothesis testing for equality of two population means using ranked set sampling and median ranked set sampling. The package gives the test results such as test statistics, p value, critical values and basic comments. In addition, using this package, it is possible to select a sample from ranked set sampling and median ranked set sampling by ranking according to auxiliary variable from a given finite population. In addition, to demonstrate the use of these tests, a real data application on Copoeta trutta fish from Elazığ Keban Dam Lake was performed.

İki bağımsız grubun yığın ortalamalarının eşitliği için hipotez testi, tıp bilimleri, tarım, biyoloji, mühendislik, sosyal bilimler gibi birçok alanda yaygın olarak kullanılan bir istatistiksel analizdir. Bu makalede, sıralı küme örneklemesi ve medyan sıralı küme örneklemesi kullanılarak iki yığın ortalamasının eşitliği hipotez testini gerçekleştirmek için oluşturulan RSStest paketi sunulmuştur. Paket, test istatistikleri, p değeri, kritik değerler ve temel yorumlar gibi test sonuçlarını vermektedir. Ayrıca, bu paket kullanılarak, verilen sonlu bir yığından yardımcı değişkene göre sıralama yapılarak, sıralı küme örneklemesi ve medyan sıralı küme örneklemesi ile örnek seçmek de mümkündür. Ek olarak, bu testlerin kullanımını göstermek amacıyla Elazığ Keban Baraj Gölü Copoeta trutta türü balıklara ilişkin gerçek veri uygulaması yapılmıştır.
