JUSTIFICATION:
Essentially, two reasons justify the existence of this unit: the need to develop a scientifically based reasoning, the capacity of presenting arguments and of communicating in scientific and technical approaches in different domains of civil engineering; the need for acquiring scientific knowledge of probabilistic and statistical nature for use in the subjects that will be studied in the remaining semesters of the course, particularly in what concerns situations involving uncertainty and decision under uncertainty.
OBJECTIVES:
To induce an educational background for other following subjects in the curricula. To give solid knowledge for future developements at the specialization level as well as at the professsional level. To prepare the student for the use of probabilistic and statistical language and to be able to comunicate when dealing with subjects in which Probabilities and Statistics take part, ensuring that a correct interiorization of concepts is achieved. To educate the student to be able to translate his reasoning into mathematics when analysing real world problems and adequately formulate these problems. To educate the student in techniques that can be used in order to solve these problems. To be able to efiently use software solving problems that require techniques or envolve statistical or probabilistic concepts. To be able to scientifically deal with situations and phenomena involving uncertainty and decision under uncertainty.
RESPONSIBILITIES AND OUTCOMES OF LEARNING:
Development skills (CDIO): technical knowledge in basic sciences (ie in Statistics), personal and professional skills of thinking and problem solving engineering, experimentation and knowledge discovery, knowledge engineering and advanced skills and attitudes ; interpersonal communication skills (oral and written).
The student should be able to:
- Describe data sets by applying statistical techniques;
- Compute probabilities in complex situations, including those that use random variables of one or two dimensions, following or not typical distributions;
- Use the properties involved in the use of typical distributions;
- Solve estimation problems
- Apreend the philosophy of hypothesis testing
- Solve problems involving the goodness of fit of distributions and discuss their fitness
- Present arguments that justify a certain solution to a problem or to express a conclusion
- Choose the best solution or the best method, when faced with an ensemble of methods or solutions
The student should have knowledge of mathematics taught in previous semesters, for example, on the use of functions of one or more variables, sequences and series and numerical analysis including the use and implementation of calculations with the help of calculators and computers.
Brief presentation of the statistical method in the context of Civil Engineering and uncertainty in Engineering.
Descriptive statistics: different types of statistical variables; univariate distributions (graphical representations and statistical measures); bivariate distributions (marginal and conditional distributions), dependency between statistical variables (shape, minimum square method, regression line, correlation coefficient).
Probability spaces (generalization of concepts, axioms, and properties, classical concept of probability, conditional probability, independence of events).
Unidimensional random variables: discrete and continuous; distribution functions; probability functions; probability density functions; brief reference to variable transformations; mathematical expectation; moments and order parameters.
Two-dimensional random variables: joint distribution, marginal distributions and conditional distributions; independence; mathematical expectation of vectors.
Typical distributions: discrete (uniform, Bernoulli, binomial, multinomial, hypergeometric, Poisson) and continuous (uniform, exponential, gamma, Gauss, lognormal, Qui2); properties of Gaussian law.
Approximations of distributions: Central Limit Theorem and most known approximations.
Estimation: statistics and estimators, estimators for the mean, the variance and the linear correlation coefficient; confidence intervals.
Hypothesis testing: philosophy of testing; goodness of fit testing.
Initiation to the simple linear regression models.

Scientific component: 85%
Technological component: 15%
DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
The thematic of this curricular unit emphasize the need to develop a scientifically based reasoning, the capacity of presenting arguments and of communicating in scientific and technical approaches in different domains of civil engineering, in particular leading to the education to deal with uncertainty in engineering; the need for acquiring scientific knowledge of probabilistic and statistical nature for use in the subjects that will be studied in the remaining semesters of the course.
It is essentially a formative subject, coordinating fundamental theoretical knowledge with some approaches which are necessary in the subjects placed ahead in the curricula. At this level it is important to develop intuitive concepts as well as computational ability. The concepts are exposed in a clear and objective way, making frequent use of examples of physical or geometrical nature. The use of statistical software is encouraged, as a working tool, namely through the execution of 2 working projects in the computer room (1 hour duration each). A total of at leat 5 sessions are held in the computer rooms and the others have intensive use of calculators. Calculators are also used during part of the written exams.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The teaching methodologies allow the students be able to describe data sets by applying statistical techniques, compute probabilities in complex situations, including those that use random variables of one or two dimensions, following or not typical distributions, use the properties involved in the use of typical distributions solve estimation problems, solve problems involving the goodness of fit of distributions and discuss their fitness, learn the philosophy of hypothesis testing.

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules.
CP: mean classification in the 2 working projects (rounded to one decimal)
CE: classification in the writing paper (rounded to one decimal)
final classification = 0,250 * CP + 0,750 * CE
NOTE 1: The distributed evaluation ran in the previous course can be transfered on demand since March, 6.
NOTE 2: The working projects are compulsory. No delivery of the working projects results in "zero" mark in the associated component.
The two working projects mentioned above (TPs) are done during laboratory classes, according to the student's schedule (see moodle).
The TPs are compulsory. Students who have their absence justified and accepted by the Degree Director will have the TP'dates altered to timetables of the other class'groupes and thus need to contact the teacher urgently, so that the new hour is set for their assessment. Only in cases for which this change is impossible the TPs will be schedulled to a day/time to be announced.
Students benefiting from special status have also to submit to the evaluation regarding the distributed component, which is compulsory, and must held either during the semester lectures or in the date stated for those who have the justified absence certified, at a date and hour to be assigned.
Students that may be candidates to special exams have to do this component no later than date date, otherwise their mark in this component to be introduced in the formula of the special exam will be zero.
Final written exam for the Written Exam Component. For the component regarding the working projects the assessment made along the academic semester remains valid.
