Statistical Graphs in Spanish Textbooks and Diagnostic Tests for 6–8-Year-Old Children

Statistical graphs are complex semiotic tools requiring different interpretative processes of the graph components, in addition to the entire graph itself. Taking this assumption and hierarchies proposed in previous research as a starting point, in this chapter we analyse the content related to statistical graphs of the Spanish curricula, textbooks and external compulsory tests taken by 6–9-year-old children. We examine the types of graphs presented to the children, the activity demanded, the reading levels required from them, as well as the graph semiotic complexity and the task context. The examples and analysis will help understand the expected progression of children’s learning of statistical graphs.
