Description
Summary:An appreciation of variation is central to statistical thinking. In this study, four students from each of grades 4,6,8 and 10 were interviewed individually on aspects of variation present in three settings. The first setting was an isolated random sampling situation, whereas the other two settings were real worlds sampling situations. Four levels of responding were identified and described in relation to developing concepts of variation. Implications for teaching and future research on variation are considered.
