Abstract: This study compares the situations proposed to address the topic of correlation and regression in mathematics textbooks from Colombia, Chile, Ecuador and Venezuela.For this purpose, we analyze how four Secondary Education textbooks from Latin American countries present situations related to association; specifically, we study the situations by identifying the problem field to which they belong, the intensity and the direction of the relationship.Under a qualitative methodology, a content analysis of the situations was carried out, considering the examples and problems proposed to the student.The results indicate that the books emphasize the analysis of the existence of a relationship between variables, while the estimation of one variable as a function of another is infrequent.In addition, situations with high relationship intensity and direct direction prevail.It is concluded that there is a need to strengthen the teaching of these contents in the textbooks analyzed.
