Results: We inform of the task difficulty according to the different variables in the questionnaire and the average reading level of statistical graphs achieved in the grades. We also inform of the main difficulties related to the different graphs and activities proposed in the questionnaire. Conclusions : We conclude that hat the students learnt by the end of the 6 th grade is remembered one year later, dot plot and pie charts were the most difficult graphs, building of graphs was difficult when the frequencies were not provided and few children attained the upper level of reading graphs.
