The main objective of the course is to make students able to carry out a quantitative analysis of real phenomena and to interpret the results. To this end, during the lessons the main tools and methods of descriptive and inferential (univariate and bivariate) statistics will be discussed, focusing on both the theoretical/methodological aspects and the analysis of real data. In particular, many examples based on real problems will be shown, especially concerning phenomena in the business, socioeconomic and financial fields. The student who is sufficient to the exam: 1) will have acquired the basic tools of statistics, such as descriptive statistics and basic inferential techniques; 2) will be able to apply all the methodologies described in the course to real data, choosing the most appropriate tools to be applied in the analysis of specific phenomena of interest; 3) will be able to interpret, discuss and criticize the obtained results. The development of this specific skill also derives from frequent discussions encouraged by the teacher, during the presentation of empirical applications; 4) will be able to communicate the methodologies as well as the results of empirical analysis with a proper language. This specific skill also derives from active participation to discussion in the classroom encouraged by the teacher; 5) will be able to to autonomously carry out statistical analyses and to understand more complex concepts and methodologies. In particular, these tools include tables and graphs, statistical indices, statistical relationships between phenomena, inferential procedures.
