Didactic methods

Lectures are conducted in the classroom with the assistance of recordings and support from teaching materials provided to students by the professor, as well as examples and exercises carried out using R.

Learning assessment procedures

The assessment of learning is done through a written exam. The exam is structured as follows:
- 15 short-answer, multiple-choice, or calculated questions
- 3 open-ended questions
The questions may cover theoretical or methodological aspects, require the solution of exercises, and ask for discussion, comments, or analysis of applied problems based on the knowledge acquired during the course.
With the exception of supplementary materials, all the topics presented in class by the instructor, the sections of the textbooks listed in the bibliography relevant to the course program, and additional materials expressly included in the lesson plan are integral parts of the learning assessment.
If inconsistencies arise in the answers provided in the written exam or it is not possible to formulate an overall evaluation of the exam, the instructor reserves the right to summon individual candidates for an additional oral exam.
The oral exam may cover any topic from the course program and may result in a final evaluation equal to, higher than, or lower than the one obtained in the written exam, potentially altering the outcome in relation to the passing grade.

Evaluation criteria

The written exam, as well as the oral exam, aim to assess the understanding of the topics in the course program, mastery of technical language, clarity of presentation by the candidate, the ability to independently apply the statistical methods learned during the course, and approach the statistical analysis of business phenomena, providing a correct interpretation of the results.

Criteria for the composition of the final grade

Voto in trentesimi.
