General description Esta materia proporciona un primeiro contacto con técnicas estatísticas avanzadas incluíndo: modelización estatística, ferramentas estatísticas para a análise de datos, procedementos de crítica e diagnose dos resultados e interpretación dos resultados en termos do problema proposto. Os obxectivos son:
- Adquirir unha visión ampla e integrada dos métodos estatísticos resaltando de cada un deles os seus obxectivos e condicións de aplicabilidade.

- Obter os coñecementos precisos para unha análise crítica e rigorosa dous resultados acadados.

- Complementar a aprendizaxe da metodoloxía co apoio de software informático

Methodologies
Methodologies Description
Supervised projects Students should develop one or two practical works related to the subject contents. These works could be defended during a pre-established seminar.
ICT practicals Practical classes in the computer lab conducted to provide some knowledge on the use of statistical software (mainly the R-commander package). These classes are specifically designed to learn the elementary use of the package and to interpret its outputs. Use of software helps to focus attention on the statistical issues rather than on the calculation.
Problem solving Solving real problems in order to use statistical techniques fluently, empashizing their practical application.
Guest lecture / keynote speech Lectures where the basic theoretical principles of the subject are presented together with properly illustrated practical examples.
Objective test Final exam on the theoretical and practical contents of the subject. This exam consists in answering a list of short questions and/or solving some longer exercises in a reasoned way.

Personalized attention
Methodologies
Supervised projects
Description
There will be personalized advice sessions during the development of the practical works. These sessions will take place by means of the interaction teacher/students at the moment of solving the different activities suggested in class: solving doubts, correcting mistakes, suggesting proper approaches to deal with the proposed problems and reviewing initial versions of the works. In addition to this, students will have the opportunity of receiving personalized advice in the office of the teachers. Personalize advice may be also received via online (e-mail, virtual platform,...).

Part-time students are not required to defend their works in class, but these works must be provided to the teachers for their assessment. Part-time students can also receive personalized assistance using both face-to-face and virtual approaches.

Assessment comments

Ongoing monitoring of attendance and ongoing assessment of knowledge acquisition by checking lists of solved problems and the learning level shown during the seminars.

The official exams of both opportunities (January and July) consist in answering a list of short and conceptual questions about the application and interpretation of the studied statistical methods.

Requirements to pass the subject are: (i) passing the official exam and (ii) performing one or two practical works where the studied statistical techniques will be used to deal with specific practical problems provided by the professors. Scores attained with these works are valid throughout the course and these requirements hold for both opportunities (January and July). If the practical works are not carried out in January, they must be performed in July. This also applies to part-time students. 

The final score could be increased up to 1 point (considering a total maximum score of 10 points) according to the results of the ongoing assessment for the student.

If the practical works are not presented in due course and the official exams are not carried out, then the specific mark "NON PRESENTADO" will be given. 

All previous observations are applicable to part-time students  and/or with academic exemption.
