How to construct a variable that measures country corruption? What does global really measure? How to design and interpret a questionnaire that captures CEO's psychological barriers to internationalize? Quantitative methods help researchers and business people approach real business problems and understand them with rigour. The objective of this course is twofold. First, after this course students will be familiar with basic statistics language as well as some applications of advanced statistics in the field of business research, so that once they face their thesis/supervised projects they can identify which method is most appropriate to answer their research question. Second, by the end of the course students will have some basic notions of how to work with the statistical software STATA. For this purpose, a teaching assistant will conduct four sessions in the computer lab where students will have to perform simple data analyses using STATA.
