Evaluation methods Verification of learning:
Knowledge and ability to understand
To verify the learning a test and an interview are scheduled. The test will consist of theoretical questions and empirical exercises on the whole program with particular attention to the use of the software R, simulating sample selection and estimation on real case studies. The final evaluation, expressed in thirtieths, takes into account both the test and the interview.
Ability to apply knowledge and understanding
During the test and the interview, students' ability to apply the knowledge of advanced survey methodologies is tested so as to be able to deal with specific case studies.
