The present study aimed to examine the contributions that a sequence of teaching based on assumptions of contextualization can bring to the teaching of statistics in the final years of basic school. The literature review concerning the teaching of statistics relies on Cazorla (2002), Lopes (2003, 2008, 2010a, 2010b), Silva (2007), Andrade (2008), Cazorla, Kataoka and Silva (2010), Jacobini et al. (2010), Campos, Wodewotzki and Jacobini (2011), among others.
