Description of contents: programme
The first objective of the course is to help the student to learn and understand of the basic concepts descriptive statistics (univariate and bivariate). These concepts include measures of centralization, dispersion and shape, basic graphics as histograms and boxplots, and scatterplots that relate the concepts of covariance and correlation. Secondly, some probability notions are introduced, like the definition of probability, one-dimensional random variables and their moments, with special attention to classical distributions, such as binomial, Poisson, uniform, exponential, normal among others. Finally, some methods of point and interval estimation are presented in order to determine the values of the parameters of the previously studied probability distributions. As a particular case, the sample mean distribution is obtained and studied. PROGRAMME 1. Introduction. 1.1. Concepts and use of Statistics. 1.2.
