标题：The effect of test instruction and risk taking tendency on psychometric properties of multiple choice tests Test yönergesi ve risk alma eğiliminin çoktan seçmeli testlerin psikometrik özelliklerine etkisi
摘要：The research is a quasi-experimental research which aims to investigate the effect of test instruction and risk taking tendency on the psychometric properties of multiple choice tests. The study group of the research comprised of 220 undergraduate students studying at different departments of Ankara University Faculty of Educational Sciences in 2014-2015 spring term. An achievement test of measurement and evaluation course consisting of 24 items was applied to students in the study group. The test was applied to four similar groups with different instructions. A risk taking scale was applied to determine the risk taking tendency of the students. The data were analyzed by using one way ANOVA, dependent sample t-test, independent sample t-test, Feldt test, Fisher’s z test, Pearson correlation coefficient, Spearman’s rank-order correlation coefficient and confirmatory factor analysis. The findings showed that corrected score means, uncorrected score means and reliability coefficients calculated from corrected scores of tests applied with different instructions were significantly different whereas reliability coefficients calculated from uncorrected scores were not significantly different. The validity of the test applied with the instruction stating that no correction for guessing would be made was the highest one. In general, risk taking tendency did not significantly change test scores.
