Statistical literacy encompasses competencies regarding the use of mathematical representations and the manipulation of data through reduction. Dealing with data referring to authentic situations, basic activities of modeling are linked to this domain of statistical literacy. Based on the recently introduced German standards emphasizing the importance of representations and modeling, our study aims at assessing competencies of middle graders in German classrooms. Therefore, a pilot study with more than 180 fifth- and eight-graders in upper secondary schools was conducted with the additional aim of testing the properties of a set of assessment tasks. The results support on the one hand typical misconceptions of students and specify on the other hand the status quo of the domain of statistical literacy in question. Using Rasch-analysis we can support the hierarchical concept.
