Abstract

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.

İstatistiğe Yönelik Tutum Ölçeği: Geçerlilik ve Güvenirlik Çalışması

Abstract

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.
