Verification of learning
THE EVALUATION OF THE PROFIT IS MADE ON THE BASIS OF A PRACTICAL TEST AND AN ORAL TEST. THE PRACTICAL TEST IS DEVOTED TO ASSESSING THE STUDENT'S CAPACITY TO APPLY THE TOOLS ACQUIRED DURING THE COURSE TO REALISTIC CONTEXTS. IT CONSISTS IN THE DEVELOPMENT OF A PROJECT WORK, USING THE STATISTICAL SOFTWARE R, IN WHICH A DATASET CHOSEN BY THE INSTRUCTOR IS ANALYSED. THE ORAL TEST, OF ABOUT 15 MINUTES, IS DEVOTED TO EVALUATING THE ARGUMENTATION CAPACITY, THE ACCURACY OF LANGUAGE AND THE ABILITY TO MAKE CRITICAL USE OF THE ACQUIRED STATISTICAL TOOLS. THE FINAL SCORE WILL TAKE INTO ACCOUNT BOTH THE WRITTEN AND ORAL EVALUATIONS.
