In view of the type of activity and the adopted teaching methods, the attendance at this activity requires the prior participation of all students in Modules 1 and 2 on safety training in the workplace, in e-learning mode.

Assessment methods

The final exam consists of the creation of a reproducible report, either individually or in groups, based on the analysis of a real dataset. The report, written in R Markdown, will be discussed during the oral exam. Submission procedures and guidelines for the report are available on Virtuale.

During the oral exam, students will be required to demonstrate knowledge of the basics of the R language, particularly the code and functions used in the report. Additionally, they must be able to explain and justify the appropriateness of the analyses conducted. Passing this assessment results in the achievement of a pass grade (idoneità).
