Örnekleme yöntemleri

Öz

Sağlıkla ilişkili çalışmaların çoğunluğu örneklemlerde yürütülür. Örneklem seçimi rastlantısal ve rastlantısal olmayan yöntemlerle gerçekleştirilebilir. Çalışma evreninin bazı özelliklerine, araştırmacının amaçlarına ve olanaklarına göre seçilen örnekleme yöntemi değişebilir. Örneklemin evreni temsiliyetini sağlaması için rastlantısal örnekleme yöntemi ile seçilmesi gereklidir. Bu yazıda psikiyatri ile ilişkili makalelerde kullanılan farklı örnekleme yöntemleri de verilerek bu yöntemlerin avantaj ve dezavantajları sunulmuştur.

Sampling methods

Abstract

Most of the studies related to health are conducted with samples. Selection of sampling may be performed with random or nonrandom sampling methods. Sampling methods may vary with respect to some characteristics of study population, researchers’ aims and facilities. It is necessary to select samples by random sampling methods in order to provide the representativeness of the study population. The advantages and disadvantages of different sampling methods are presented in this manuscript which are used in psychiatry related articles.
