General description Esta materia introduce os conceptos básicos da análise estatística de datos, desde a análise exploratoria (incluindo as principais ferramentas gráficas) ata a inferencia estatística, pasando pola introducción á probabilidade, o concepto de variable aleatoria e as ferramentas fundamentais do control estatístico da calidade, enfocando a súa docencia para a resolución de problemas prácticos en enxeñaría industrial.

Study programme competencies
Code Study programme competences
A1 Capacidade para a resolución dos problemas matemáticos que poidan formularse na enxeñaría. Aptitude para aplicar os coñecementos sobre: álxebra lineal; xeometría; xeometría diferencial; cálculo diferencial e integral; ecuacións diferenciais e en derivadas parciais; métodos numéricos; algorítmica numérica; estatística e optimización.

Methodologies
Methodologies Description
Guest lecture / keynote speech The main contents of the subject will be explained with the help of suitable audiovisual means (laptop and video canon).
Problem solving Problem-solving seminars will be held in intermediate-sized groups in order to establish the concepts presented in the master sessions and to provide knowledge of the methodologies for the practical resolution of statistical problems.
ICT practicals Part of the practical classes will be carried out in a computer lab where, with the help of a statistical package (free software R), different practices will be developed using real or simulated data, previously provided to the students.
Objective test At the end of the couse, a test type exam composed of 15-20 questions (practical and theoretical concerning with the subject contents) will be done.

Methodologies
Guest lecture / keynote speech
Description
There will be lectures where the teacher will explain, with the help of appropriate audiovisual media (laptop and video projector), the main contents of the course. Encouraged at all times the debate among students and between students and teacher.

In the case of students with academic dispensation, person-to-person and virtual tutorials (e-mail, videoconferences) will be available, which will allow the student to follow properly the subject.

Assessment comments
<b>Evaluation at the first opportunity</b><p>The
mark of the objective test will be weighted with the score
corresponding to the optional delivery of works related to the practices
carried out with statistical software R (maximum 1.5 points) and with
the mark corresponding to the attendance at class (1 point), being necessary to obtain at least a score of 3.5 out of 10 in the objective test to be able to make this compensation.</p><p><strong>Evaluation at thesecond opportunity</strong></p><p>The evaluation will be done following the same procedure as at the first opportunity.</p><p>In
the case of students with recognition of part-time dedication and
academic exemption from attendance that decide not to attend classes,
will be evaluated in the two opportunities as the rest of the students
who are in a similar situation.</p>
