Learning Objectives

The aim of the course is to provide the basics of the calculus of probability, with particular interest to the probability theory, random variables and probability functions, as well as the main concepts of inferential statistics.

Bridging Courses

It is recommended, but not mandatory, to have done the Calculus exam.

Learning Achievements (Dublin Descriptors)

Knowledge and understanding: the student will be acquainted with the basis of the mathematical theory of Probability and of the Inferential Statistics.

Applying knowledge and understanding: the student will be able to theoretically analyse problems where stochastic variability plays a fondamental role.

Making judgements: the student will be able to choose among several approaches the suitable solution to probabilistic problems.

Communication skills: the student will be able to communicate probabilistic informations by use of the techniques of the differential and integral calculus.

Learning skills: the student will learn the methodology to be used in the mathematical formulation of empirical phenomena.

Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Teaching, Attendance, Course Books and Assessment

Teaching

Frontal lectures.

Attendance

The attendance at courses is not mandatory.

Course books

P. Baldi, "Calcolo delle Probabilità e Statistica", McGraw-Hill.

R. Lupini, "Lezioni di Probabilità e Statistica", Quattroventi.

W. Navidi, "Statistics", Mc Graw-Hill.

D. Posa e S. De Iaco: ”Fondamenti di statistica inferenziale”, CLEUP.

S. Ross: ”Probabilità e statistica per l’ingegneria e le scienze”, APOGEO.

Assessment

The exam of Probability and Statistics consists of a written exam and an oral one, both of them mandatory.
The written exam, to carry out in two hours, consists of exercises related to the topics of the course. The written exam is passed if the mark is, at least, 15/30. During the written exam it is not allowed to use textbooks, workbooks or notes. Moreover, it is not allowed to use mobile phones, under penalty of disqualification.
The oral exam consists of a discussion related to the topics of the course. The oral exam can be taken only if the written one has been passed. If so, the oral exam can be taken only in the same call in which the written exam has been passed or in the other calls of the same session.
The evaluation of the oral test considers the acquired knowledge, the understanding of the subject, and the ability to present the subject matter strictly.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
