00914 - Statistics

Learning outcomes

By the end of the module the student should know the basic themes of statistics either from a methodological and an applied perspective. In particular the student should be able to: - summarize statistical data using distributions and graphs - select and compute the most appropriate summary statistics (mean values and variablity measures) - measure the strength of the association between two characters observed on the same set of units.

Assessment methods

The goal is to verify the learning of basic Statistics, as well as the critical abilities developed by the student in choosing the most appropriate tool for a given problem. The exam for the Statistics module consists of an oral test. The test involves solving exercises and answering various theoretical and reasoning questions on topics covered during the course. For the part of the test related to Probability Calculus content, please refer to the consultation of Guideweb for that subject.

The overall grade for the integrated course takes into account the results of the two modules and is expressed in thirtieths.
