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.
Short answer questions Multiple choice and short answer questions to assess the progress for each unit of the subject. They will be online using moodle.udc.es.
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

The
objective tests, in each of the two opportunities, will consist of multiple
choice and short answer questions, related to the application of the studied statistical
methodologies and the interpretation of the corresponding results. The
supervised projects will be practical projects in group, with the
implementation of some of the different statistical methodologies to a real
data set given by the teacher/s, using statistical software (R). The score of
the supervised projects will be kept during the current academic course. In
case one (or both) supervised project(s) is (are) not submitted for the first
opportunity in January, it (they) may be submitted for the second opportunity
in July. 

To pass the subject, it will be
strictly necessary to pass each block separately. Otherwise, if only one or no
blocks are passed, the final score will be 4.5 at most. 

To pass each block, it
is necessary that the score of the objective test, for this block, is not lower than 3 out of
10 and the global score of all the assessment activities of the block is not lower than 4.5 out of 10.

For any of the two opportunities to pass the subject,
the “NON PRESENTADO” grade will be given only to the students who did not
submit any of the supervised projects nor take the objective test.

All these remarks are applied to the
part-time students and/or with academic exemption.

All these remarks are applied to the December session exam

Fraud
in tests or evaluation activities will
directly involve the implementation of the current rules in the Assessment, review and complaint regulation of the UDC and the  Student Statute of the UDC
