Abstract
This study situates early notions of average within an inquiry classroom to investigate the rich statistical concepts young children draw on to make sense of the questions: Is there a typical height for a student in Year 3? If so, what is it? Based on their deliberations over several lessons, students’ ideas about average evolved through four conceptions - typical as: reasonable, most common (value or interval), not atypical, and representative of the population. Implications for teaching are discussed.
