The student will have to take into account the contents of the exam will be based both in the matter explained in class and in the bibliography of recommended study each topic. Theoretical module: Test consists of 30 questions with three possible answers. It is necessary to approve a five to pass the course. Correction formula (Gulliksen 1950): Note = [Aciertos/30] * 10 Practical Module: An evaluation by submitting a scientific paper about building model to explain and predict a psychological phenomenon, and reliability analysis and validation, together with a team practical notebook. The work will be performed in groups of 6 people. In the team practical notebook information of teamwork skills are collected. Those who do not participate in the work development will be excluded as authors. It is necessary to approve a five to pass the course. In different calls to the regular February, the assessment of this module will be using a 30 question multiple-choice test with three possible answers for each question (correction formula (Gulliksen 1950): Note = [Aciertos/20] * 10). * Attendance at practical classes: - Attendance is not mandatory. - For those students attending the practical sessions will score the job done in the classroom. In each practice session groups must carry out each of the phases of construction and model validation. This work must begin and end in the corresponding session as scheduled practices. This means that the groups who come to class each session must have all the necessary equipment to carry out the same, including the database. Otherwise, attendance at practice is counted as zero. The session will score of 0.05 points on the note of the final report. * Final Memory Contents: The student will make a report following the format of a research paper, which will be reflected in the contents of all practices: theoretical framework, description of the sample, variables and instruments, model building and analysis of reliability and validity. FINAL NOTE SUBJECT: Arithmetic average of the grades for each of the modules. Only half will be the achievement of at least a score of 5 on both sides, ie, if any part of the course will obtain a grade less than 5, the student will fail the course. Since the course consists of two parts that students must pass in order to overcome it, in each call shall be deemed that the student was brought to the course if you have any of the two, is the theory exam or delivery of the final 'memory. The ratings shall conform to the provisions of RD 1125/2003 of 5 September.
