Methodologies
Methodologies Description
Guest lecture / keynote speech Lesson given by the teacher that may have different formats (theory, problems and/or general examples, general guidelines of the subject, etc.). The teacher might use audiovisual and computer means. In addition, s/he can introduce some questions posed to the students.
The objective is to introduce the student into the concepts of the subject, in order to transmit the knowledge base the student needs to start his/her work and his/her learning.
Workshop The main objective in these classes will be the realization of especially practical tasks, with the teacher's support and supervision: proposal and solution of applications from the theory, proposal and supervision of works, problems, exercises, presentations, expositions, debates and comments on works, solving doubts about the theory, etc..
It is also possible that the teacher explains some concepts, especially for clarifying their application, or in any case as a mere comment about the keynote speech.
ICT practicals The main objective in these classes will be the development of especially practical tasks, with the teacher's support and supervision. The computer is employed in these classes, which are reserved for lessons or concepts where the intensity of the calculations needs the computer tool. In addition, the students are introduced into the work with Statistics by using computer means.
Mixed objective/subjective test Written test used for evaluating the learning. This test may consist of a combination of different formats of questions, as exercises, test, etc.. The final objetive is that the student develops his/her capacity of reasoning and the teacher has a tool for assessing the knowledge, skills and abilities of the students.
Two mixed test will be carried out: the first one covers the lessons on Descriptive Statistics, Time series and Index numbers; the second one corresponds to the lessons on Probability Calculus.
Collaborative learning Work in groups of students in order to solve the tasks assigned by the teacher to optimize their own learning and that of the rest of classmates.
Before handling the work in groups, several classes will be dedicated to pose the doubts and/or difficulties found when doing the work. In this manner, a debate is created among the students, their classmates and the teacher, who encourages the interrelation in the work and the critical spirit.

Long answer / essay questions Written test with answers of certain amplitude. This test can be a combination of exercises belonging to different lessons, with short questions and/or multiple choice questions.
This test allows for measuring the knowledge the student is acquiring and, in this manner, analyzing his/her evolution in the subject.

Seminar Technique for working in groups. Each group will be divided into two sub-groups of students.
There will be tutorial sessions with a total duration of 4 hours per student distributed along several sessions. These sessions may be used for developing the practical tasks supported by TICs, to solve doubts related to problems or to prepare the exam. The place and the hours for these sessions will be announced sufficiently in advance in class.
Speaking test Activity designed to respond orally to questions, specially assessing the capacity of reasoning. It allows for measuring different abilities of the student. This activity may also include the realization and exposition of practical exercises (type I and type II). The exposition will be individual, although its realization and evolution can combine individual cases and/or cases in groups.
Type I exercises: individual exercises that the students will develop along the different classes at the teacher's proposal.
Type II exercises: exercises in groups based on bulletins provided by the teachers; although they do not have to be identical, they will be of the same style.
The participation of the student in class will be evaluated in this section. The selection of the type of activity or activities to carry out will be subject to the teacher's criterion.

Assessment
Methodologies Competencies Description Qualification
Mixed objective/subjective test A4 A6 B7 For the purpose of motivating the continued and well-distributed work of the student, the teacher will carry out a first mixed test (first assessment test). This exam covers the lessons on Descriptive Statistics, Time series and Index numbers (lessons 1 to 4), and it represents the 40% of the final mark.
The second mixed test (second assessment exam) corresponds to the lessons on Probability Calculus (lessons 5 to 8) and it is done in the same date as the final (official) exam; it represents the 30% of the final mark.
70
Speaking test A10 C5 C6 C7 C8 This activity allows for assessing the student's participation in class. The type/s of speaking test will be under the teacher's criterion. The activities susceptible to be assessed would be: attendance to class, the answer to questions posed by the teacher, the realization and exposition of practical exercises in class (either individual or in groups) or any other kind of activity designed for the initial purpose.

10
Collaborative learning A12 B10 C1 It constitutes the realization of the work in groups.
The work consists of learning how to deal with a spreadsheet in order to apply the statistical techniques developed in class. The work will be evaluated in the computer room. The teacher might consider the attendance to the training sessions in the computer room as a part of the work.
The work will be assessed following the teacher's criterion.

Long answer / essay questions C1 C6 C7 They will be developed in the second part of the subject. It is a written exam with questions of certain amplitude. It might include short questions and/or multiple choice questions.

Assessment comments

The exams and evaluation activities of the subject will only be carried out according to the planned dates, except for an exceptional cause, under the teacher's criterion. The dates for developing the mixed test and the long answer questions will be announced in class sufficiently in advance.

The mixed tests (assessment tests) are considered essential for the evaluation; for this reason, it is necessary to obtain at least a 40% of the total mark in each one of them, that is, a mark of 4 points, so as to compute with the remaining evaluation activities.

The first assessment exam will be considered as "passed" conditioned to obtaing a mark equal or higher than 4 points. If this first exam is "passed", in the final (official) exam it will only be necessary to do the second assessment exam.

The students who have not reached the minimum mark in the mixed tests (assessment tests) but with a mark higher than 5 points in the global count of the evaluation will not have passed the subject and their mark in the final act will be 4.5 points.

The subject will be passed when at least five points (or more) were obtained in the global count of the subject, conditioned to have reached the minimum mark in the assessment tests.

For the students who have "passed" one part of the subject by means of a mixed test (assessment test): this fact will only have validity for the current academic year. If a student with one part of the subject "passed" is not able to pass the whole subject in the opportunities of June or July, his/her final mark will be "failing" and he/she will have to re-take the whole subject in the folowing academic years.

Those students interested in raising their mark can take the final exam, with prior notification to the teacher and his/her consent.

Evaluation criteria for the second opportunity will be the same as the one applied in the first opportunity. If a student underwent the advanced announcement, the same criteria than in the second opportunity will be applied in order to pass this subject. In this case, it means a 70% for the exam and a 30% for the mark obtained in the continuous evaluation. 

With respect to the "Absent" mark and according to the regulation approved by the Faculty Board, the people that only take part
in evaluation activities whose total weight is lower than the 20% of the
final mark will get "Absent" as their final mark.    

Following the rules approved by the Faculty Board, it is forbidden to
enter the classroom where the evaluation activities are being held with
any device that allows for communicating with the outside and/or
information storage.
