In this paper we report on our ongoing efforts to identify and assess key ideas in data analysis (or statistics) that we maintain should be at the focus of middle school instruction. It was in the hopes of locating items that we could use to assess some of these more complex objectives that we searched the collection of items released by the National Assessment of Educational Progress (NAEP) and the various states. We first describe in more detail the nature of items being used on large-scale state assessments. We then offer some of our views on what we should be teaching and present some items that we are designing to tap these ideas.
