Objectives and Contextualisation
Learn the basic statistical theoretical basis for the analysis and comprehension of information prepared by the competent bodies in the field of security and by statistical observatories.
Master the formulation necessary to prepare and adjust for themselves the statistical information to their own specific environments, both public or private activity, where they develop their function in the future.
Have the ability to infer and make forecasts and forecasts and know the relevant variables and their management in scenarios of risk, uncertainty and competition.
Use basic tools and computer programs, complementary to the content of the subject.
Competences
- Apply specific software tools to solve problems specific to security.
- Be able to communicate efficiently in English, both orally and in writing.

Methodology
Students must study the teaching units provided, which are enough to progress in this subject. Recommended bibliography should be considered as a helping tool. There will be several virtual sessions that will allow the student to review the content that he/she has been individually working on.
They also must deliver the PECs previously arranged in the calendar.
For the completion of PEC 0 it is required to research and collect data from, among others, the recommended.
Tutorials with the teaching staff will be arranged by email, upon request.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
1-Individual theoretical-practical test
Final test to do individually, in any format: test, development or resolution of exercises. This test will be required to pass the subject and will be done at the scheduled date and time. Under the criteria of continuous assessment, this test will weight in the final grade, as established in the table, of 40%.
Not passing the subject, and according to the criteria of the continuous assessment, a re-take test is offered on the scheduled date and time. The test will gather the entire content of the program. In order to do this re-take, there must be evidence of evaluation during the course of at least 2/3 of the content used to assess the final grade. However, after the re-take, the final grade will be no more than 5-Pass.
If you need to change the date of any test, the petition must be submitted by filling out the document you will find in the moodle EPSI Tutorial space.
["If the student makes any irregularities that may lead to a significant variation in the qualification of an evaluation act, this evaluation act will be classified with a 0, regardless of the disciplinary process that can be instructed. produce different irregularities in the acts of evaluation of the same subject, the final grade of this subject will be 0 ".]
2 -Online individual theoretical and practical tests - periodic exercises
Individual resolution of tests, to be delivered periodically. The number of these tests will be determined at the beginning. Their evaluation will be based on:
- Timely delivery of the proposed PECs. It is required to deliver at least 2/3 of them. Those not delivered will be graded as 0 (zero)
- Quality of the exhibitions and answers
- Understanding and mastery of the subject
- Additional contribution that deepens the subject (penalizing plagiarism)
- Ability to express and summarize
- Do not copy literal texts of the teaching material provided
They can be done by sharing knowledge with other members of the subject but the delivery will be individual. The delivery will be virtual within the arranged deadlines. The average in the grades of these tests (0 to 10) will have a weight in the final grade of the subject of 30%.
3 - Long-term assignment
Long-term evaluation serves as a recopilatory work of the subject. Its topic and content will be specified at the beginning of the course. It will be evaluated based on:
- The quality of content and analysis, as well as the orderly and attractive presentation
- The use of the statistics studied in the course
- The variety and actuality of used sources
- The ability to analyze the information
- The ability to predict and extrapolate, given the analysis
- Analysis and conclusions of the work carried out
The presentation of the work is required to qualify the subject. Working on it is individual. You can not share your elaboration with other members of the course.
Important! The grading will be from 0 to 7, with a weigth in the final grade of the subject of 30%. Up to this point, with the 3 blocks explained, a maximum score of 9.1 may have been obtained. The rest of the grade is pending up to a maximum of 10 points for the block that is explained below.
4- Continuous evaluation - multiplier
Tracking will be evaluated throughout the course. It is intended to see the evolution during the course, as well as the domain at the end of it. For example, a forum of doubts supervised by the teacher of the course will be provided. The approach and resolution of doubts, sharing ideas or proposals to solve the PECs (without giving an explicit solution), etc.
In short, on the grade obtained in the previous sections, a multiplier will be applied between 1.00 and 1.10, at the discretion of the teacher (e.g., grade 9.1 * maximum multiplier 1,1 = 10, or grade 7, 2 * remarkable multiplier 1,07 = 7.7). The non-delivery of tasks or cases in which plagiarism is detected will involve a multiplier of less than 1.

| Final project | 30% | 0 | 0 | 2, 1, 3, 6, 4, 5, 9, 8, 7 |
| Understanding and correct use of concepts and formulas or applications in the realization and delivery of the works and exercises required on-line. | 30% | 0 | 0 | 2, 1, 3, 6, 4, 5, 9, 8, 7 |
| Written or oral tests to assess the knowledge acquired by the student | 40% | 0 | 0 | 2, 1, 3, 6, 4, 5, 9, 8, 7 |
