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.

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
