Examining statistical literacy skills within high-stakes assessment

This study investigates statistical items from high stakes tests (i.e., PISA, TIMSS, and Indonesian National Exams (UN1)) based on five skills of statistical literacy. The five skills comprised of understanding, interpreting, evaluating, communicating, and decision-making. The findings of this study revealed that most of the statistical items in TIMSS and UN assess understanding, while in PISA assess all skills except decision-making. Furthermore, TIMSS and PISA item features are more diverse than UN’s since it only provides multiple choice. This study provides evidence that the three existing high-stakes assessments are not adequate to understand the Indonesian students’ statistical literacy.
