چکیده مقاله :
هدف اصلی این مطالعه ساخت و اعتبار یابی مقیاسی فارسی برای سنجش میزان اضطراب آمار و هدف فرعی تعیین رابطه اضطراب آمار با جنسیت ، نوع دیپلم و سن دانشجویان دانشگاه آزاد اسلامی آبادان بود. به این منظور 319 دانشجو(129 پسر و 190 دختر) که در نیمسال دوم سال تحصیلی 86-1385 در کلاس های آمار ثبت نام کرده بودند به شیوه نمونه گیری خوشه ای انتخاب شدند. پرسشنامه ابتدائی شامل 47 گویه بود که 17 گویه آن در مراحل مختلف تحلیل آماری حذف شد. روائی سازه با تحلیل عاملی نشان داد که 30 گویه برروی پنج عامل قرار میگیرند. برحسب محتوا این عامل ها بترتیب خرده مقیاس های اضطراب کاربرد آمار، تحلیل و تفسیر آمار،امتحان آمار، ابزار آمار و معلم آمار نامیده شدند. پایایی مقیاس کلی اضطراب آمار و خرده مقیاس های آن با ضریب پایائی آلفا کرنباخ و روش بازآزمائی تأئید شد. برای اثر متغیرهای جنس، نوع دیپلم و سن بر اضطراب آمار دانشجویان از آنالیز واریانس سه راهه استفاده شد که نشان دهنده اثر معنی دار متغیرهای جنس و نوع دیپلم بر اضطراب آمار و عدم اثر معنی دار بین سن و اضطراب آمار بود. آزمون تعقیبی نشان داد که برای متغیر جنس دانشجویان دختر اضطراب آمار بیشتری در مقایسه با دانشجویان پسر دارند و برای متغیر دیپلم، دانشجویان با مدرک دیپلم انسانی در مقایسه با دانشجویان با مدارک ریاضی، تجربی و فنی حرفه ای اضطراب آمار بیشتری را دارند.
The aim of this study is constructing and validating a Persian scale for measuring statistical anxiety among students of Islamic Azad University in Abadan. The minor aim is to determine its relationship with gender, age, the field of study in high school. The statistical sample size included 319 student s (129male &190female) who were enrolled in second term in statistics course, were randomly selected using cluster sampling. The initial questionnaire included 47 items, 17 items of which were deleted due to initial statistical analysis. The reliability of factorial analyses of 30 items were put on five factors, namely: application statistical anxiety, analyze and comment of statistical anxiety, examining statistical anxiety, statistical anxiety instrument, and teachers’ statistical anxiety. Using alpha coefficient and test -retest methods, the reliability of total statistical anxiety scale and subscales were confirmed. Three way ANOVA was used for determining effects of gender, age and field of study in high school on the statistical anxiety. The findings indicated that main effects of gender and field of study in high school were significant on statistics anxiety. Post hoc test indicated that female students had greater anxiety than the male students. Also scheffe test indicated that students studying in humanities during high school had greater statistical anxiety than the other students.
