Academic Year 2019/2020 - 1° Year

5 CFU - 2° Semester

**STATISTICS**Method of teaching course:

Lectures, active participation of students through questions, preparation of a questionnaire for data collection and subsequent data collection and exercises.**Information processing system**The aim of the course is to provide a set of scientific-disciplinary skills related to the design and implementation of information processing systems, as well as their use in various application contexts.

The main technologies related to information systems and the theoretical bases on information processing systems will be provided with particular attention to system architectures, modern operating systems and computer networks. The course will also focus on spreadsheets with a particular focus on their use for solving exercises related to the world of medical statistics.
