### 5.1. Methodological overview

The methodology proposed for this subject is to promove the continued work in the student focuses on both actual data treatment and the introduction of the fundamental aspects of Statistics. In sessions with the whole group theoretical aspects are based in the form of master class complemented by its application to solving real problems. Treatment with actual data is done in sessions in the computer lab where you learn to manage statistical computer programs.

The course is divided into four hours of class a week for 15 weeks. Two hours are for exposure of theoretical concepts and examples, in the complet group, and the other two hours to develop skills in planning, resolution and interpretation of realistic problems, in the lab class.

A problem is proposed a each student for to resolve. In addition throughout the course application proposed in a real case of the techniques presented . This activity will take place continuously during the course, making periodic reviews .
