SOURCES AND METHODS FOR THE ANALYSIS OF INTERNATIONAL DATA

EXPECTED LEARNING OUTCOMES

 

Knowledge and understanding

The students will become familiar with the International Official Statistics and their sources, and with the main concept of statistical data analysis.

Applying knowledge and understanding

The students will be able to extract data from the official statistics data sources, to manipulate them with excel, to compute basic statistics and estimate some basic statistical models.

Further expected learning outcomes:

  • Making judgements: Decide which is the best data source related to the problem and the most adequate statistical techniques for the analysis.

  • Communication skills: Students will present their results through a written report and an oral presentation.

  • Learning skills: They will be able to search for additional data sources and to understand more complex statistical methods.
