Probabilities and Statistics
Data Science
-
ApresentaçãoPresentationThe curricular unit Probability and Statistics belongs to the scientific area of Statistics and provides the probabilistic and inferential foundations required for data analysis. It develops skills to model random phenomena, perform statistical inference and support data-driven decision making, constituting a fundamental curricular unit in Data Science.

MetodologiaMethodologyThe teaching methodology includes the expository method (TM1) to present the contents, the demonstrative method (TM2) to illustrate its application to practical cases and the active method (TM3) to solve classroom exercises, with and without the use of a computer. Whenever appropriate, statistical software is used to explore concepts, interpret results and support the solution of real-world data analysis problems.
