Abstract
When Year 10 students are introduced to reasoning from box plots the type of classroom discourse that will lead them to understand statistical inferential argumentation is unknown.
In this paper the discourse of one teacher and her class is analysed. Although the teacher required evidence for claims and introduced statistical vocabulary, she argued with the medians, lacked uncertainty, did not answer the original question or make sense of the conclusion. The implications for teaching are discussed.
