This study investigated what is taught and learnt with regard to relations of confidence interval and sample size when students were facilitated to reason about the graph of sampling distribution of sample means. For this aim, a teaching experiment was designed and implemented by researchers and teachers in the model of co-learning inquiry. Based on anthropological theory of the didactic, the praxeological analysis was conducted. Observed similarities and differences between the taught and learnt praxeology were discussed.

Mots clés: Anthropological theory of the didactic; didactic transposition; confidence interval; sample size
