## Learning outcomes

------------------------
MM: STATISTICA MEDICA E EPIDEMIOLOGIA CLINICA
------------------------
The course aims to make students able to: describe and interpret the informations about a set of data; know and interpret the main measures of frequency and association in the epidemiological field.
------------------------
MM: INFORMATICA APPLICATA
------------------------
The course aims to provide students with basic knowledge on the functioning of a computer and on archiving and management of health data. Students will use the spreadsheet for data synthesis and representation, and they will retrieve information from bibliographic databases.
------------------------
MM: PSICOMETRIA
------------------------
The lectures are focus on two aims related to the collection of data trough a questionnaire. The first aim concerns the construction of a new questionnaire, the adaption of an existing instrument and the different ways of data collection. The second aim concerns an introduction on the R package software for data analysis to be able to verify the psychometric properties of the questionnaire.
