Evaluation methods Verification of learning:
The exam consists of a written test lasting 1 hour and 45 minutes, with various exercises aimed at verifying the mastery of the statistical methodologies, the processing capacities and the interpretative capacity of the results obtained. The test contains data to be processed, multiple choice questions and discursive answers regarding the interpretation of the results obtained, for a total of about 15/20 exercises.
Afterwards (same day), an oral interview will take place, which always starts from the discussion of the written test, to then converge, eventually (if the elements deriving from the test are not sufficient to reach an evaluation) on questions concerning the topics of the program not included in the written test.
The joint evaluation of the test and the oral interview will lead to a final single mark in thirtieths.
