Entropy Measure to Compare the Internet and Face to Face Surveys

Abstract

Technological improvements are utilized in data collection methods as in all areas of life. The expansion of computer and Internet use make it possible to conduct a survey on Internet. Today, many researchers take advantage of this opportunity. This paper seeks to answer whether there is any significant difference between data collection methods as Internet and face to face. To reach this objective response patterns from two data collection methods and from two different scales (Cetscale and Self-Efficacy) are investigated by using an entropy measure. Findings reveal that internet based survey provides less dispersed responses for selfefficacy scale in which social desirability effect is less than Cetscale. Furthermore our results provide evidence that scales have also influences over dispersion of responses.

Entropi ölçümü ile İnternet’ten yapılan anketler ve yüz yüze yapılan anketlerin karşılaştırılması

Abstract

Teknolojideki değişim hayatın her alanında olduğu gibi veri toplama yöntemlerinde de kendini göstermektedir. Bilgisayar ve İnternet kullanımının yaygınlaşması araştırmacılara İnternet ortamında da anket yapabilme olanağı sağlamaktadır. Günümüzde de bu olanaktan gittikçe artan bir şekilde faydalanıldığı görülmektedir. Bu çalışmada, Internet ortamında yapılan anketler ile yüz yüze yapılan anketler vasıtasıyla elde edilen veriler arasında farklılık olup olmadığına cevap aranmaktadır. Bu amaçla, iki farklı veri toplama yönteminden ve iki farklı ölçekten (Cetscale ve öz-yeterlik) elde edilen veriler entropi ölçüsü kullanılarak analiz edilmiştir. Bulgular, Internet temelli anketlerin öz-yeterlik ölçeği için daha az dağınık cevaplar sağladığını göstermektedir. Ayrıca sonuçlar, ölçeğin yanıt dağılımı üzerinde de etkisinin olduğuna dair kanıtlar sunmaktadır
