Abstract: 

In this paper an experimental study of students' strategies in solving a judgment of association in scatter plots is presented. The classification of these strategies from a mathematical point of view allows us to determine concepts and theorems in action and to identify students' conceptions concerning statistical association in scatter plots. Finally, correspondence analysis is used to show the effect of task variables of the items on students' strategies.
