No specific prerequisites are required for this subject.
This subject is an introduction to statistics. Its objective is to transmit its usefulness in the analysis of data and the design of experiments and, to show which are the most appropriate tools according to the objectives of the study and the available data.
1. DESCRIPTIVE STATISTICS: Exploration of data
1.1 Variables versus individuals. Qualitative and quantitative variables
1.2 Graphical representation
1.3 Summary statistics
1.4 Scatter plots and correlation
1.5 Contingency tables
1.6 Introduction to the linear regression model
2. INTRODUCTION TO PROBABILITY: Random variables and distributions
2.1 Concept of probability
2.2 Properties of probability
2.3 Random variables
2.4 Some useful distributions: Binomial, Poisson and Normal
2.5 Notions about the Central Limit Theorem
3. STATISTICAL INFERENCE FOR VARIABLES
3.1 Introduction to statistical inference
3.2 Notions of experimental design, type of studies and sampling
3.3 Parameter estimation and confidence intervals
3.4 Contrast of hypothesis: concept and reasoning. Significance level (p-value)
3.5 Inference for the population mean. paired data
3.6 Inference for two means comparisons
3.7 Inference for proportions
3.8 Inference for the mean in more than two populations (ANOVA)
3.9 Nonparametric tests
4. STATISTICAL INFERENCE FOR ASSOCIATIONS BETWEEN VARIABLES
4.1 Contingency table. Chi-square test
4.2 Inference by the correlation coefficient
4.3 Simple linear regression model
5. NOTIONS ON STATISTICAL MODELING
5.1 Concept of response variables and predictor variables
5.2 Models for quantitative response variables
5.3 Models for qualitative response variables
To reach the contents of this subject it will be necessary to follow both the directed activities (master classes, problems and practices with computers) and the work of individual study outside the classroom.
The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
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.

The evaluation of this subject will be done with the practical sessions and the realization of problems. Apart there will also be two global tests.
The qualification of practices will be done through two tests where several exercises will be performed using the software learned in these sessions.
The first evaluation does not release matter. The final evaluation will therefore include all the theory taught during the course. To pass the subject it is necessary that the weighted average of the marks (exams, practices and problems) is at least 5 and that the final exam grade is higher than 4. Students who do not pass the final exam can submit to the final exam. a recovery exam. To participate in the recovery of students must have been previously evaluated in a set of activities the weight of which equals a minimum of two thirds of the total grade of the subject
The grade of "Not evaluable" will be applied to the students when the evaluation activities carried out have a weight lower than 67% in the final grade.
Student's assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
