Abstract

Nowadays, the topics of statistics and probability appear frequently in different contexts of everyday life, which makes it necessary to train future citizens, from the first years of compulsory education, to interact effectively with this information. For this reason, in this research, the activities proposed in the statistics and probability units in the seventh and eighth year textbooks of Basic Education in public and private editions were analyzed, identifying various aspects of them, such as, type of statistical graph, reading level, level of semiotic complexity, type of task and type of context. A qualitative methodology was used, based on the interpretive paradigm. A total of 100 activities and 249 tasks were analyzed, in which a predominance of the bar graph is concluded, reading level 2 (reading between data), semiotic complexity level 3 (representation of a data distribution), type tasks justify and personal context. Regarding the contents and general objectives that must be presented in both texts, public and private education, differences found are described in relation to how the activities that are proposed in each of them are addressed.
