Abstract (2. Language): 
The aim of the current study was to develop a Statistics Attitude Scale to determine the statistics attitudes of university students in social sciences. The data was collected from the students attending to the various programs in Pamukkale University, Faculty of Education, including Social Sciences Education, Science Education, Mathematics Education, Computer Education and Instructional Technology, Psychological Counseling and Guidance. The participants were a total of 450 randomly selected university students (296 female and 154 male ). The scale is a 9- point- Likert- type scale with level of agreement varying from “I definitely do not agree” (1) to “I definitely agree” (9). In order to test validity, exploratory factor analysis was conducted. The result of the Exploratory factor analysis revealed five dimensions: the Relation of Statistics and Professional Life (7 items), Statistical Anxiety-Fear (9 items), Enjoying Statistics (6 items), the Importance of Statistics (6 items), and Statistical Difficulty Perception (4 items). Cronbach Alpha coefficient was calculated as 0.927 for internal reliability indicating the scale has a high degree of internal reliability. In summary, the Statistics Attitude Scale has both high levels of validity and internal reliability.
Abstract (Original Language): 
İstatistiğe yönelik tutumları ölçme aracı geliştirmek amacıyla yapılan bu çalışmada, Çalışma evreni olarak Pamukkale Üniversitesi Eğitim fakültesinde 2011-2012 eğitim-öğretim yılında öğrenim gören, istatistik dersi veya istatistikle ilgili olarak bir ders alan, öğrenciler oluşturmuştur. Araştırma örneklemi ise söz konusu evrenden tesadüfi yöntemle belirlenen 296’sı bayan ve 154’ü ise erkek öğrenciden oluşan toplam 450 öğrenci oluşturulmuştur. Ölçek geliştirme aşamasında 58 istatistik tutum maddesi oluşturulmuş, bu maddelerin madde-toplam korelasyonlarının hesaplanmasından sonra, madde toplam-korelasyon değerleri düşük olan maddeler ölçekten çıkarıldıktan sonra 33 madde verileri kullanılarak Açımlayıcı Faktör Analizi (AFA) yapılmıştır. AFA sonuçlarına göre ölçekte yer alan 33 madde beş faktör (İstatistiğin mesleki yaşantı ile ilişkisi faktör öz değeri 10,019 ve açıkladığı varyans oranı %30,362, İstatistik korkusu-kaygısı öz değeri 3,980 ve açıkladığı varyans %12,061, İstatistikten keyif alma öz değeri 1,970 ve açıkladığı varyans 5,971, İstatistiğin önemi öz değeri 1,432 açıkladığı varyans ise %4,338 ve Algılanan istatistik güçlük faktörünün ise öz değeri 1,178 ve açıkladığı varyans ise %3,569’dur) altında toplanmıştır. Beş faktör toplam varyansın % 56,301’ini açıklamaktadır. Beş faktör altında yer alan 33 maddelik ölçeğin tümü için iç tutarlılık anlamında Cronbach ⍺ = 0.927 olarak hesaplanmıştır. Ulaşılan bulgular eldeki istatistiğe yönelik tutum ölçeğinin geçerlilik ve güvenirlik özelliğine sahip olduğunu destekler mahiyettedir.
