Abstract

Meta analysis may be defined as the quantitive review and synthesis of the results of related but independent studies. The use of meta analysis as a technique for quantitive research synthesis of multiple studies has become increasingly popular. By combining information over different studies with same issue, an integrated analysis will have more statistical power than an analysis based on only one study. In this paper, it is aimed to give information about features and use of meta analysis and explain difficulties confronted with in meta analysis.

Meta Analizi

Abstract

Meta analizi, ilişkili fakat bağımsız çalışma sonuçlarının niceliksel gözden geçirilmesi ve sentezi olarak tanımlanabilmektedir. Çoklu çalışmaların nicel sentez tekniği olarak, meta analizinin kullanımı hızla yaygınlaşmıştır. Aynı konudaki farklı çalışmalardan bilgi toplayarak yapılan birleştirme analizi, sadece tek bir çalışmaya dayanan analizden daha fazla istatistiksel güce sahip olacaktır. Bu makalede, meta analizinin özellikleri ve kullanımı hakkında bilgi verilmesi ve meta analizinde karşılaşılan güçlüklerin açıklanması amaçlanmıştır

Keywords

meta analizi, heterojenlik, yanlılık
