The increasing prevalence of data emphasizes the importance of statistical literacy. Educational systems are charged with developing students who are statistically literate before entering higher education or the workforce. Adequate teaching and learning of statistics in K-12 education faces challenges, due to limited statistical content knowledge and the effects of noncognitive factors on teaching. The study employed structural equation modeling to analyze the interrelationships among statistics teaching efficacy, attitudes toward statistics (subscales: affect, cognitive competence, difficulty, and value), and anxiety about statistics. Results indicated primary preservice teachers with positive attitudes toward their statistical knowledge exhibited higher confidence in teaching statistics. Additionally, low anxiety about statistics significantly predicted positive attitudes across all subscales. Mediation analysis revealed teachers' low anxiety about statistics enhanced positive attitudes toward knowledge and intellectual skill in using statistical knowledge, subsequently boosting statistics teaching efficacy. This research highlights the role of noncognitive factors in teaching statistics and provides insights for teacher preparation programs to enhance statistical literacy education. By addressing noncognitive aspects of teacher development, teacher preparation programs can better equip preservice mathematics teachers to foster statistical understanding in their future students. Focusing on the development of noncognitive factors can help cultivate competent, confident, and enthusiastic teachers about teaching statistics, fostering a culture of statistical literacy essential in today's data-driven world.
