Objectives
Introductory course in Probability and Statistics: acquisition of basic concepts and application to real situations.
Particular attention will be paid to the presentation and understanding of the concepts, keeping the mathematical treatment at a median level.
Learning outcomes and competences
On completing this curricular unit, the student is expected to:
- understand the concepts involved in a statistical study and be aware of the various problems that arise in each particular study;
- correctly identify and apply the learnt techniques from Descritive Statistics, used to summarize data, and to interpret them;
- master the the probability concepts and calculus approached in the curricular unit;
- be able to characterize random variables/vectors and to identify the correspondent probability distributions;
- be able to make simple statistical inferences on basic population parameter,s from point and interval estimation techniques.

Program
1. Probability Theory: fundamental concepts, independence of events and conditional probability, the Bayes’ and the total probability theorems.
2. Univariate random variables: definition, probability (density) function and probability distribution function; expected value and its properties; variance and its properties.
Bivariate random variables; joint distributions; covariance and correlation; independent random variables.
3. Some probability distributions: discrete distributions (uniform, binomial, multinomial and Poisson) and continuous distributions (uniform, normal, exponential, chi-squared and Student's t). The De Moivre-Laplace and the Central Limit Theorem.
4. Descriptive Statistics: fundamental concepts, types of observations and measurement scales, techniques for data summarization (tables, plots, measures of location and scale), outliers, Pearson's correlation coefficient.
5. Statistical Inference: random sample, statistic, sample mean and sample proportion.
Point estimation: properties (bias and consistency).
Some sample distributions. Interval estimation: computation and interpretation of confidence intervals for some population parameters.

Calculation formula of final grade
Final classification obtained by a distributed assessment:
Final mark = 0.4xT1 + 0.6xT2
where
T1 = the first test rating (0-20)
T2 = the second test rating (0-20)
T1 >= 8.0 and T2 >= 8.0
Final classification obtained by examination:
mark of the final exam.
The students will be sucessful in the curricular unit once the final grade (obtained either in the tests or in the final examination) is greater than or equal to 9.5.
Students with a score greater than or equal to 17.5 values in the final exam must make a complementary written or oral exam in order to obtain a final score greater than or equal to 18 values.
Examinations or Special Assignments
Exams under speacial conditions will consist of a written test or oral test which can be preceded by an oral eliminatory exam.
