The aim of this subject is that students learn:

- to consider an economic problem in statistical terms,

- to solve manually and by means of the statistical program R-Commander,

- to correctly interpret the results,

- to elaborate study reports.

This course is devoted to study:

- The main distributions of probability

- Statistical inference.

RA01: Identify relevant economic information sources for the company and their content.

RA02: Understand economic institutions as the result and application of theoretical or formal representations of how the economy works.

RA03: Derive relevant information for the company from data that cannot be recognized by non-professionals.

RA20: Plan, organize, and control global management projects or those of the different functional areas of the company.

RA25: Use personal, social, and methodological knowledge, skills, and abilities to issue advisory reports on specific situations of companies and markets.

RA29: Develop the skills necessary to understand and apply quantitative techniques to the interpretation and resolution of socioeconomic problems.

Learning Activities:

Lectures A-1

Practice sessions A-2

Individual or teamwork projects or problem-solving A-3

Individual or small group tutorials A-4

Individual work A-5

Exam A-6

Self-evaluation A-7

Lectures will be devoted to introducing the subject basic contents that will be illustrated with practical activities to help students to develop individual-study habits. Lectures and practice sessions will be alternated for all chapters.

Practice sessions will have two different approaches. Either they will consist of in-class problem-solving sessions of some proposed exercises by the professor or the students or they will consist of practice sessions with computers so that students will be required to use some statistical software as a tool to solve problems and practical cases. Lesson notes, as well as any other teaching material, will be available in MiAulario.

Learning outcome | Assessment activity | Weight (%) | It allows test resit | Minimum required grade |

In-term tests | 30% | Yes | No | |

Final exam | 70% | Yes | No |

The evaluation method may include activities such as practice sessions, in-term tests made with or without a computer, problem-solving based on computer-obtained outputs, and attendance during office hours.

The final exam will include questions about theoretical and practical topics studied in the course. These questions may consist of problem-solving questions, test-type questions, and/or solving economic problems using statistical tools.

The makeup exam will contain questions about theoretical and practical topics studied in the course. This exam retakes the whole course and therefore its weight is 100%.
