Specific skills acquired Profes Acquiring the tools of descriptive statistics plays an obvious role in the development of the sional following professional skills by the students (skills associated to the FB English line of study): skills • The adequate use of the concepts, theories, methods and tools specific to finance, for the well functioning of the private or public organizations; • Collecting, analyzing and interpreting the data and the information connected to economic and financial problems; • The ability to write economic and financial papers (academic, or professional reports) for the private or public organizations. Trans versal skills 7. The courses and the seminars of descriptive statistics play a role in the development of all the transversal skills (associated to the FB English line of study): - Applying the principles, the norms and the ethical values of the profession such that the graduates are able to construct a rigorous, efficient and responsible strategy of work; - The ability to identify the roles and responsibilities within a team of complex tasks, being able to insure with the rest of the teammates an efficient team work; - The ability to identify the opportunities for continuous professional development and the efficient use of all the identified resources and techniques. - The knowledge of and the ability to apply the general principles and the theory of the market economy. Course objectives (arising from grid of specific skills acquired) 7.1 General objective of the discipline 7.2 Specific objectives 8. The general purpose of the course is to prepare the students to apply methods and procedures of inferential statistics to any economic field, within both the academic world and the business real world. Students should acquire the fundamental notions and techniques of inferential statistics; Students should be able to apply the techniques of inferential statistics in financial and economic problems; Students should be able to use SPSS in understanding and applying the tools of inferential statistics in economic and financial problems.

Corroboration / validation of the discipline content according to the expectations of the epistemic community representatives, of the ones of the professional associations and also of the representative employers of the corresponding program. Inferential statistics is one of the main courses providing the students information on how to jointly apply economic theory, mathematics and statistical techniques for the purpose of testing hypotheses, estimating and forecasting economic phenomena. Therefore, it is a course of vital importance for the professional development of any undergraduate in any economic field that needs quantitative assessments. 10.
