A Japanese version of the Self-efficacy for Statistical Literacy Scale was developed. In a preliminary study with college students (N = 110), a Japanese translation was developed based on the English version of this scale. In Study 1, the resulting Japanese version was verified in terms of validity and reliability with high school and college students (N = 275). Results from Study 1 showed that self-efficacy for statistical literacy is positively correlated with subjective numeracy and critical thinking disposition. The mathematical score positively predicted self-efficacy for statistical literacy. In Study 2, we considered the extent to which self-efficacy for statistical literacy would change between before and after statistics education among high school students (N = 167). Results from Study 2 suggested that self-efficacy for statistical literacy is enhanced by statistics education. Free-text descriptions provided by the participants revealed that they could accurately interpret numerical values and had higher interest in the study of psychology and their future career options. Potential contributions to education and study limitations are discussed.
