The course is concerned with the description and discussion of the main statistical tools useful to collect, organise and analyse data, in order to make a valid support for business and financial strategic decisions. Through the use of business cases and applications, the course aims at providing operational and practical guidance to data analysis, useful to those who, in various corporate functions, are involved in collecting, analyzing, processing and evaluating qualitative and quantitative information related to the company data. The knowledge and skills acquired at the end of the course are useful to address more effectively both the study of the advanced statistical courses, like "Statistics for Marketing", "Statistics for Finance", "Statistics for business decisions", "Statistics for the Risk Management", and the empirical analysis supporting the final thesis for the Laurea Magistrale. In particular, the course aims to (i) provide the ability to use quantitative techniques for the analysis and interpretation of social, economic, financial and business phenomena and (ii) develop the skills and personal attitudes of analysis necessary to acquire consulting abilities, especially in the field of market research, and to learn the most advanced theoretical methods developed in the quantitative disciplines, which are needed to fully achieve the aims of every programme of the Laurea Magistrale.
