Abstract:

Regression and correlation (bivariate data) these methods are used to measure the relation between variables. In this work we have discussed techniques to study the relation between two variables, from the construction and interpretation of scatter diagrams, the method of least squares to determine the curve of best fit, to the calculation of the coefficients of correlation and determination, as well as the way to interpret them. The platform contains the development of the subject with exercises, and the section called Aprendiendo.com. In the last section, it provided to the student an interactive environment, using the available resources on Internet, in such a way that those cases raised to develop them learning environments that allow find knowledge, "handle it" and understanding. With this philosophy, applets, Web sites with access to real data, free software and in the resources of the Web 2.0, referring to a second generation in the history of the Web based on user communities that foster the collaboration and fast exchange of information between them.

The objective was to adapt the themes of bivariate data, in the subjects of statistics which are taught in the FESC, an e-learning model in order to (a) optimizing their contribution to the content, skills and competences that students must have (b) integration of statistical software in courses to highlight applications to problems and real contexts of concepts and methods; (c) the development of interactive materials that facilitate updating and learning by experimentation; (d) the use of a model of continuous assessment that guide and prepare the students in their training; and (g) the promotion of collaborative learning online by assigning projects and activities to be carried out in working groups.

Using information technologies allows us to implement a new concept of the use of the modern statistics to the students and this tells us that it is not important to memorize formulas or perform complex arithmetic calculations. Instead you can focus on results in a faster way using some kind of technology (software, advanced calculators, specialized web sites, etc) to give a practical sense to the results through critical thinking.
