| KNOWLEDGE AND UNDERSTANDING. STUDENTS WILL GAIN KNOWLEDGE OF: - DESCRIPTIVE STATISTICS AND THE MAIN TOPICS OF STATISTICAL INFERENCE - STATISTICAL ANALYSIS OF ECONOMIC DATA AND DECISION MAKING UNDER UNCERTAINTY IN MANAGEMENT PROCESSES - STATISTICAL MODELS FOR DATA ANALYSIS AND THEIR APPLICATIONS IN REAL CASES APPLYING KNOWLEDGE AND UNDERSTANDING. THE COURSE AIMS AT HELPING THE STUDENTS TO DEVELOP THE ABILITY TO USE STATISTICS METHODS AND MODELS ON TOPICS MAINLY RELATED WITH MANAGEMENT AND FINANCE. THEORETICAL RESULTS AND EMPIRICAL EVIDENCES WILL BE GIVEN TO ALLOW A PROPER PROCEDURE IN THE CHOICE AND THE INTERPRETATION OF THE RESULTS IN EMPIRICAL APPLICATIONS ON REAL DATA SET. |

| THE COURSE CONSISTS OF 60 HOURS OF LECTURES. EACH LESSON IS STRUCTURED IN A THEORETICAL PART AND A PART OF APPLICATIONS IN CASE STUDIES. GIVEN THE CHARACTERISTICS OF THE DISCIPLINE, THE ATTENDANCE IS STRONGLY RECOMMENDED, ALTHOUGH NOT MANDATORY. |
| Verification of learning | |
|---|---|
| THE EXAMINATION CONSISTS OF TWO COMPULSORY PARTS, A WRITTEN TEST AND AN ORAL INTERVIEW. EACH PART IS ASSIGNED A MARK AND THE AVERAGE OF THESE MARKS IS CONVERTED INTO THIRTIETHS TO GIVE THE FINAL GRADE. AN EXAM IS DEEMED TO BE PASSED SUCCESSFULLY IF THE FINAL GRADE IS EQUAL TO OR HIGHER THAN 18/30. IN THE EVENT OF A FULL GRADE (30/30), THE EXAMINATION BOARD MAY GRANT HONOURS (LODE). THE ORAL INTERVIEW CAN ONLY BE TAKEN ONCE THE STUDENT HAS PASSED THE WRITTEN EXAM WITH A MINIMUM MARK OF 18/30. THE WRITTEN TEST TAKES ABOUT 75 MINUTES AND AIMS AT ASSESSING THE ABILITY TO APPLY THE ACQUIRED KNOWLEDGE AND THE ANALYTICAL INSTRUMENTS. THE TEST IS STRUCTURED IN THREE PARTS WITH NUMERICAL EXERCISES ON: DESCRIPTIVE STATISTICS, PROBABILITY AND RANDOM VARIABLES AND STATISTICAL INFERENCE. THE ORAL INTERVIEW TAKES ABOUT 20 MINUTES WITH A DISCUSSION ON THE THEORETICAL AND METHODOLOGICAL TOPICS PRESENTED DURING THE COURSE TO ASSESS THE LEVEL OF KNOWLEDGE AND THE ABILITY AND THE QUALITY OF ORAL EXPOSITION. |
