The course provides an introduction to probability theory and statistics through applications typical of civil and environmental engineering. The course is divided equally into traditional lessons and computer laboratories in which the student learns to deal with realistic problems involving quantities affected by uncertainties.
The course introduces the theory of probability and statistics as tools for the representation and analysis of random phenomena typical of the field of study. The mathematical bases of the discipline are defined starting from the general definitions to arrive at operative tools in order to represent and manipulate random or uncertain quantities. The discussion is supported by examples that cover the spectrum of applications foreseen in the following courses. Applications are performed on the computer using the Matlab programming environment.
The course has two learning outcomes, which are complementary. The first objective is stated in the title and concerns the understanding of the fundamentals of probability and statistics.
The study starts with a general mathematical approach necessary to clearly formulate the problems dealt with. Mathematical tools able to represent and manipulate variables affected by uncertainties are developed. General criteria for making decisions in contexts where the available data are uncertain or the amount of information is limited are discussed. Following this introduction, the course deals with typical applications of civil and environmental engineering that anticipate, by placing them in the common framework of probability theory, problems faced in subsequent courses.
The second learning aim (not declared in the title, but not less important) consists in learning the IT tools necessary to implement the mathematical techniques and solve the problems treated. Basic notions on programming in the Matlab environment are provided and numerous guided exercises in the computer lab are held.
The coexistence of the two objectives mentioned is justified by two observations supported by experience: (1) it is not possible to teach probability and statistics without having the possibility to use computational tools for the practical solution of realistic problems; (2) it is not possible to learn how to program a computer without having real problems to face and solve. The ambition of the course is therefore to translate these two weaknesses into a strength.
Lectures: on the blackboard using projections
Tutorials: in the computer laboratory. Students perform computer exercises in small groups, followed by the teacher. In the final part of the course, the exercises are organized in order to simulate an exam.
