The master's thesis focused on relationships between statistics anxiety, academic procrastination, and trait anxiety in university students. There were 512 students of University of Ljubljana (UL) who completed the following questionnaires: the Statistics Anxiety Rating Scale (Cruise, et al., 1985), Academic Procrastination Scale (McCloskey, 2011), and State – Trait Anxiety Inventory (Spielberger et al., 1983). The results showed that UL students experienced statistics anxiety and procrastinated with academic obligations below average levels. Student females reported higher trait anxiety and statistics anxiety than males, but they procrastinated less. Gender and trait anxiety were significant predictors of statistics anxiety. The results also showed that students differed in experiencing statistics anxiety according to their views on mathematics and statistics. Students of different faculties differed in experiencing statistics anxiety. In the study, we translated and adapted the questionnaire for measuring statistics anxiety to Slovenian language. The confirmatory factor analysis confirmed the six-factor structure of the questionnaire. The results provide basis for further research on statistics anxiety and further validation of the STARS questionnaire.
