	Objectives
	THE COURSE HAS THE TWOFOLD PURPOSE OF: I) ILLUSTRATING THE MAIN METHODOLOGIES OF INTEREST FOR STATISTICAL DATA ANALYSIS; II) APPLYING SUCH METHODOLOGIES TO RELEVANT PRACTICAL PROBLEMS, USING TOOLS COMMONLY EMPLOYED FOR STATISTICAL ANALYSIS, DATA VISUALIZATION AND PROCESSING. KNOWLEDGE AND UNDERSTANDING. •ACQUISITION OF THE MAIN STATISTICAL INFERENCE AND DATA ANALYSIS. •PARAMETRIC VS. NON PARAMETRIC APPROACHES. SUPERVISED VS. UNSUPERVISED APPROACHES. •ACQUISITION OF THE MAIN TECHNIQUES AND TOOLS FOR BIG DATA ANALYSIS. APPLICATION KNOWLEDGE AND UNDERSTANDING. •ABILITY TO APPLY THE MAIN TECHNIQUES FOR STATISTICAL INFERENCE AND DATA ANALYSIS TO PRACTICAL PROBLEMS (E.G., SOCIAL OR BIOMEDICAL DATA). •ABILITY TO EXAMINE BIG DATA, ARRANGED IN RATHER COMPLEX AND/OR HETEROGENEOUS STRUCTURES • ABILITY TO USE SOFTWARE (E.G., R, MATLAB) FOR STATISTICAL DATA ANALYSIS, DATA VISUALIZATION AND PROCESSING. •ABILITY TO USE TOOLS OF PRACTICAL INTEREST FOR DATA ANALYTICS (E.G., APACHE SPARKS) .

	Teaching Methods
	THE COURSE INCLUDES THEORETICAL LECTURES AND CLASSROOM EXERCISES ALSO WITH THE USAGE OF COMPUTERS.

	Verification of learning
	THE FINAL EXAM CONSISTS OF DISCUSSING A PROJECT WORK, AIMED AT EVALUATING: THE KNOWLEDGE AND UNDERSTANDING OF THE CONCEPTS PRESENTED DURING THE COURSE; THE ABILITY OF SOLVING STATISTICAL-DATA-ANALYSIS PROBLEMS APPLYING THE METHODS AND TOOLS ILLUSTRATED DURING THE COURSE. FURTHERMORE, THE PERSONAL JUDGEMENT, THE COMMUNICATION SKILLS AND THE LEARNING ABILITIES ARE ALSO EVALUATED.
