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 naval e oceánica.
Contingency plan 1. Modifications to the contents
The lessons are not modified.
2. Methodologies
*Teaching methodologies that are maintained
Teaching methodologies that are maintained
• Practices through ICT.
• Problem solving.
• Mixed test.
Teaching methodologies that are modified
Tools: Moodle, Microsoft Teams and email.
* Temporalization: Teams will be used as a tool to give the theoretical an practical lessons and the tutorials. Moodle will be used for the publication of content and notices, and for the evaluation of students (continuous evaluation and exam). E-mail will serve as a tool to resolve doubts and to exchange files and information in general.
3. Mechanisms for personalized attention to students

4. Modifications in the evaluation

All methodologies and their weighting in the global mark will be maintained: Problem solving (10%), consisting of the delivery of exercises; practices through ICT (60% of the global mark), defined by the presentation of works proposed by the teachers with the free statistical software R; and the mixed test (40%), consisting of a test-type examination consisting of between 15 and 20 questions, both practical and theoretical, about the subject of the course (it will be carried out in distance mode and also in the synchronous mode).

5. Modifications to the bibliography or webgraphy

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.
Mixed objective/subjective 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.

Personalized attention
Methodologies
Guest lecture / keynote speech
Description
There will be lectures where the teacher will explain, with the help of appropriate audiovisual media, the main contents of the course. Debate will be encouraged 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.

All teaching methodologies are maintained, changing only the mechanisms of personalized attention to students, which will consist of virtual classes and virtual tutorials.

Assessment comments
Evaluation at the first opportunity

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 3 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.

Evaluation at thesecond opportunity

The evaluation will be done following the same procedure as at the first opportunity.

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.

To help to achieve a sustainable environment and meet the objective of action number 5: “Healthy and sustainable environmental and social teaching and research” of the "Green Campus Ferrol Action Plan:

1.- The delivery of the documentary works carried out in this subject:

1.1. It will be requested in virtual format and/or computer support.

1.2. It will be done through Moodle, in digital format without the need to print them

1.3. If done on paper:

-Plastics will not be used.

- Double-sided prints will be made.

- Recycled paper will be used.

- Draft printing will be avoided.

2.- A sustainable use of resources and the prevention of negative impacts on the natural environment must be made.

3.- The importance of ethical principles related to the values ??of sustainability in personal and professional behavior must be taken into account.

4.- As it is included in the different regulations of application for university teaching, the gender perspective must be incorporated in this subject (non-sexist language will be used, bibliography of authors of both sexes will be used, intervention in student class will be encouraged and students ...).

5.- We will work to identify and modify prejudices and sexist attitudes, and the environment will be influenced to modify them and promote values ??of respect and equality.

6. Situations of discrimination based on gender must be detected and actions and measures will be proposed to correct them.

7. The full integration of students who, due to physical, sensorial, psychic or sociocultural reasons, experience difficulties in an ideal, egalitarian and profitable access to university life will be facilitated
