Oral and written communication.

The content of the program has been structured into three blocks: The Block I (point 1), devoted to the descriptive statistics, whose aim is to provide the student knowledge and understanding of the basic concepts of descriptive statistics of data sets univariate and bivariate analyzes. These concepts include measures of centralization, dispersion and form, basic graphics as histograms and boxplots, and scatter diagrams correlating with correlation coefficients and with linear regression. In the Block II (points 2,3 and 4), dedicated to the probability and ramdom variables, we will provide the student with knowledge of probability and one-dimensional random variables and its moments, with emphasis on the binomial distributions, negative binomial, geometric, Poisson, Pareto, uniform, normal, log-normal, Student's t test, chi-square, gamma, exponential, Weibull and beta. There are knowledge and understanding of dimensional variables, and basic concepts, as well as on linear combinations of random variables. Concludes with the study of the Central Limit Theorem. In the Block III (points 5-6), dedicated to the Statistical inference, introduces the concept of sampling distribution to derive conclusions on one (or two) population (s) unknown (s). This target is achieved by means of the calculation of intervals of confidence, the parametric hypothesis contrast for one or two populations, and the nonparametric hypothesis contrast hypothesis of goodness of fit and independence. There becomes special emphasis on the concepts of p-value and potency of the contrast of hypothesis introduced. The last topic is related to Simulation (Monte Carlo and bootstrap methods) and applications. Each topic exercises must be conducted using the R software. PROGRAM Topic 1: Introduction.

THEORY (4 ECTS): Theoretical classes with material of available support in the Web (collection guides / slides and exercises, basic bibliographical material and complementary material to study in depth those topics in which they are more interested). There will develop the fundamental theoretical and practical concepts of the subject that the pupil must acquire, and exercises will be solved on the part of the teacher, encouraging the active participation of the students in the resolution of the same ones (both of individual form and in team(equipment)). PRACTICES (2 ECTS): Classes of problem solving on the part of the pupils. Computer practices in computer rooms. Oral presentations and discussions.
