Objectives
The objective of this course is for the student to acquire a set of tools or skills related to Statistics both at a theoretical and applied level. -Proficiency to analyze and synthetize the main information content in a set of univariate and multivariate data. -Proficiency to compute probabilities and statistical moments at different dimensions -Proficiency to use random variables as a statistical device to model real phenomena. -Proficiency to identify the appropriate probability model for specific real situations. -Knowledge of the properties of point and interval estimation methods, with the aim of doing statistical inference. -An Proficiency to use statistical models as well as the Proficiency to perform an optimal estimation of the parameters by maximizing the likelihood and minimizing the prediction errors. -Proficiency to formulate and testing hypothesis about a population. -Proficiency to design lineal models that help to understand and predict real phenomena. -Proficiency to use statistical software.

Learning activities and methodology
The learning methodology consists on the following elements: -Lecture class will be taught in face-to-face mode (0.8 ECTS): Presentation of the main statistical concepts, with their justification and examples. The instructor will illustrate the methodologies with the computer and real or simulated data. Discussion of the concepts with the students. Discussion of the questions and doubts aroused during the self learning process. -Exercises class (0.8 ECTS): Classes devoted to solving exercises in small groups. -Lab class (0.2 ECTS): The students solve data analysis problems by using a statistical package. They are asked to solve exercises and conceptual problems by using the statistical software. After each class and organized in small groups, they are asked to make a case study that will be evaluated. -Tutorials (1.1 ECTS): Individualized or group assistance to students by the teaching staff with 25% attendance. -Individual or group work (2.9 ECTS). -Final exam (0,2 ECTS).
