Primary school students reasoning about and with the median when comparing distributions

Résumé

Statistical reasoning can be enhanced at an early stage by facilitating informal statistical reasoning and developing conventional measures based on individual conceptions. This paper aims at identifying young students´ conceptions of the median and their relations to its definition. For this, we present a design research study with grade 3 students (age 9) focusing on the comparison of two groups. The qualitative analysis of complementary interviews shows that young students already develop an initial understanding of the median but struggle to find the conventional reference for the middle. Consequences will be drawn for further design cycles.
