The primary goal of this article is to provide detailed instructions as to how to run a mindset intervention in a psychology statistics course. A secondary goal is to provide preliminary data on such an intervention's relationship to students' statistics anxiety and course grades. Large randomized studies have demonstrated that using a one-time mindset intervention can have positive benefits for students' course outcomes. We adapted this approach to design an intervention that includes a 75-minute presentation on what mindsets are, how are they are related to learning, and strategies for students to learn statistics with a growth mindset and, thereby, reduce their anxiety. Data from N = 75 students split into an experimental and comparison group suggested that receiving the intervention resulted in students' mindsets becoming more growth oriented and that this was related to a decrease in anxiety and an increase in course grade.
