  • Abstract
    Reading and building statistical graphs are part of the statistics literacy that well informed citizens need to critically face the information society. In this paper we first analyse the graph elements and the semiotic activity involved in graphical work. Then, we discuss the definition of graphical understanding, and the graph understanding levels. Next, we focus on errors in reading and building graphs, the use of graphs in exploratory data analysis, and teachers’ understanding of graphs. The conclusion of our analysis is that graphical competence is neither reached by students nor by prospective primary school teachers. Consequently, this survey provides information that can be used in improving the graphical competence of students and teachers as well as the didactical education of teachers.
