The demand for STEM graduates has remained consistent over the past decade, and is anticipated to further increase as the next decade unfolds. Difficulties regarding mathematics within introductory courses has been cited by participants as a contributing reason for transferring out of STEM fields of study, or avoiding these fields entirely. Substantial amounts of research has explored the relationship between anxiety, including math anxiety, and academic achievement. This research has provided empirically based results which are able to be utilized by higher education institutions as a means of improving their support systems for students with math anxiety. Despite the vast amount of research, there has been limited research exploring the relationship between math anxiety and personality. This study examined the relationship between personality traits and self-reported math anxiety within postsecondary students (n = 161). Multiple linear regression analysis revealed that a relationship exists, and that the personality dimensions of emotionality and openness to experience are positive predictors, while extraversion is a negative predictor. Consistent with previous research, a significant gender difference was observed in reported math scores, with female responses being significantly higher than males. Additionally, the average math anxiety score observed within this study was significantly increased in comparison to the normed sample for the math anxiety scale which was established nearly two decades ago, indicating that math anxiety remains a pervasive challenge to our educational system. The author recognizes that while a relationship between personality traits and math anxiety was identified, a medium effect was also found, and that the amount of variation accounted for by the predictive model generated from the analysis was low, suggesting that further research is needed for larger generalization of the findings.
