Bibliography
Classroom slides (uploaded on Elly after 2/3 of the course) are the reference point for the exam. Some further reference books:
- WW Daniel and CL Cross - Biostatistica, concetti di base per l’analisi statistica delle scienze dell’area medico-sanitaria - Ed. EdiSES;
- SA Glantz - Statistica per discipline biomediche - McGraw-Hill.
Teaching methods
During the classroom lectures the topics of the module program will be illustrated and commented. Each theory argument with mathematical formulae will be explained through simple and practical examples, to allow students focusing on basic concepts more than the formulae themselves.
Lectures will be held on-site in compliance with safety standards, provided that further instructions on the ongoing health emergency are not implemented. Supporting material will be available on the specific, student-reserved platform (Elly) and will include slide presentations.
Assessment methods and criteria
The assessment of the achievement of module objectives includes:
- creation of work groups made by 3-5 students;
- analysis and presentation of a scientific paper each group;
- creation of an online questionnaire (Google form, surveymonkey etc) and data presentation.
