Current curriculums recommend the use of technological resources in the teaching of statistics, due to the help they represent in the calculation and production of graphs, the work with real data and the learning of several concepts through simulation. In this research, we analyse the different technological resources suggested in high school textbooks for teaching and learning bi-dimensional statistics in high school (organization and representation of bi-dimensional data, correlation and regression).The importance of this issue is due to the fact that it extends functional dependence to random situations and provides students with opportunities to model numerous applications. On the other hand, previous research shows many difficulties of understanding and misconceptions on these topics. The researchers analysed sixteen Spanish text books, using content analysis; eight books of each of the two modalities that include this topic: "Humanities and Social Sciences" and "Science and Technology". In these books was analysed the use of technological resources in the problems and procedures proposed, the references to technological resources in Internet and the content of a CD that supplements most of these textbooks. The results suggest a scarce presence of these resources in the textbooks analysed, and a large variability of the resources described. The reference to Internet resources is often reduced to didactic units and not to data sets that can be used in projects or simulators to facilitate conceptual understanding. The CD which supplements some of these textbooks sometimes reproduces the same text which appears in the book or includes collections of traditional exercises; there are few problems and procedures based on technology. Finally, some recommendations for improvement of these texts are presented, considering technological resources.
