Data Collection, Administrative Sources and Big Data

Objectives

This curricular unit aims to present a set of methodologies that support data gathering in the process of producing official statistics, including data collection processes (mainly in the context in which data collection takes place through surveys based on a questionnaire), the use of administrative data and the use of sources associated with what is commonly referred to as Big Data.

At the end of the curricular unit the student should achieve the following learning objectives:
1. Identify and differentiate methods of data collection.
2. Know and select the most appropriate data collection methods and modes for each situation.
3. Be able to design a data collection methodology based on a survey.
4. Identify potential administrative sources and methodological aspects in their use
5. Recognize the potentialities of the use of big data in official statistics and the methodological aspects in their use

Teaching method

 This course is based on theoretical-practical classes including the presentation of concepts and methodologies, practical aplications, methodological discussions, and project/exercise resolution.

Evaluation method

The evaluation includes a final exam (60%) and an optional  project (40%).
The project includes the development of a report that should be discussed with the professor. The project comprehends the design of a methodology to support a data collection for a real problem.
To ensure approval it is necessary to achieve a minimum score of 8.5 in each component of assessment.
