Abstract

Bu çalışmada doğru kullanım ve yorumlama ile güven aralıklarının araştırmalarda sunulmasının önemi üzerinde durulmuştur. American Psychological Association (APA) (2010) yayım kılavuzu, güven aralıkları değerlerine çok önem vermekte ve çalışmalarda rapor edilmesi gerektiğini belirtmektedir. Araştırmacılar tarafından eksik ve yanlış da yorumlanabilen güven aralıkları bu çalışmada ayrıntılı olarak ele alınmış, kitaplardan da örnekler verilerek doğru ve yanlış tanımlar değerlendirilmiş ve görsel sunum ile örneklendirilerek okuyucuların güven aralıkları konusunu daha kolay anlamaları amaçlanmıştır

Keywords

Understanding Confidence Intervals With Visual Representations

Abstract

In the present paper, we showed how confidence intervals (CIs) are valuable and useful in research studies when they are used in the correct form with correct interpretations. The sixth edition of the APA (2010) Publication Manual strongly recommended reporting CIs in research studies, and it was described as “the best reporting strategy” (p. 34). Misconceptions and correct interpretations of CIs were presented from several textbooks. In addition, limitations of the null hypothesis statistical significance test (NHSST) were discussed, and using CIs was discussed as an alternative to the NHSST. Finally, the calculation and the visual representation of CIs for mean and effect size were illustrated to help readers comprehend the concept of CIs
