Objectives
KNOWLEDGE AND UNDERSTANDING:
-ACQUIRE THE MAIN TOOLS OF DESCRIPTIVE STATISTICS AND STATISTICAL INFERENCE
-ACQUIRE MAIN TOOLS FOR BUSINESS ORIENTED DECISION MAKING
-ACQUIRE KNOWLEDGE OF STATISTICAL MODELING WITH APPLICATIONS TO REAL DATASETS

APPLYING KNOWLEDGE AND UNDERSTANDING:
STUDENTS WILL BE EXPOSED TO CASE STUDIES TO UNDERSTAND THE ADVANTAGES GAINED FROM APPLYING STATISTICAL ANALYSIS TO QUANTITATIVE PROBLEMS ARISING FROM BUSINESS MANAGEMENT.

MAKING JUDGMENTS:
THE METHODS COVERED IN THIS COURSE ARE WIDELY APPLIED TO THE STUDY OF FIRM LEVEL MICROECONOMIC PROBLEMS. STUDENTS WILL BE REQUIRED TO APPLY METHODS TO REAL DATA AND COMMUNICATE ON THE INTERPRETATION OF THE RESULTS.

COMMUNICATION SKILLS:
THE CLASSES WILL FOCUS ON THE PRESENTATION OF THE RESULTS OBTAINED APPLYING STATISTICAL METHODOLOGIES ON REAL DATASETS. THE EMPHASIS WILL BE PUT ON THE USE OF GRAPHICAL TOOLS AND SUMMARY STATISTICS AS RELEVANT INFORMATION DEVICE SUPPORTING THE DECISION MAKING PROCESS.

LEARNING SKILLS:
THE LECTURE WILL AIM TO STIMULATE THE STUDENT'S QUANTITATIVE INTELLECTUAL ABILITIES. STUDENTS WILL BE ASKED TO DEVELOP THOSE SKILLS NEEDED TO STUDY FURTHER QUANTITATIVE PROBLEMS WITH A HIGH LEVEL OF AUTONOMY.

Teaching Methods
THE COURSE IS ORGANIZED IN 60 HOURS OF LECTURES. LESSONS MAY INCLUDE AN APPLICATION PART, WITH REAL DATA EXAMPLES.
Verification of learning
THE EVALUATION IS BASED ON A WRITTEN AND AN ORAL EXAMINATION. THE WRITTEN EXAM CONSISTS OF THEORY (40%) AND PRACTICAL NUMERICAL EXERCISES (60%). EACH OF THE TWO PARTS OF THE WRITTEN EXAM CONSISTS OF QUESTIONS WORTH 1-8 POINTS. THE EXAM IS PASSED WHEN THE STUDENT ACHIEVES AT LEAST 60% OF THE TOTAL SCORE. THE ORAL EXAMINATION IS AN IN-DEPTH DISCUSSION ABOUT THE TOPICS OF THE WRITTEN EXAMINATION.
