An introduction to basic statistical concepts on data analysis, stressing on the role of Statistics in Economy and Business.
Topics of interest will cover sources of statistical data, data files management; descriptive analysis of univariate and bivariate data real data; description and analysis of temporal data. The use of different statistical packages will be fundamental in data analysis. Basic notions of probability and random variables are also introduced.
At the end of the semester students must be able to:
LO1 - Understand the notions of Univariate and Bivariate Descriptive Statistics and apply them according to the different types of variables to be analyzed.
LO2 - Analyze the temporal evolution of socio-economic data studying time series analysis.
LO3 - Use software for data handling.
LO4 - Prepare and submit reports on statistical analysis of economic data obtained consulting appropriate information sources and computer processing.
LO5 - Understand the notion of probability, know its properties and apply them to solve problems arising from socio-economic environments.
From a total of 60 hours, 40 will be devoted to theoretical, problem and computer sessions.
The remaining period will be devoted to check students individual progress and to evaluate their work. These sessions will be scheduled along the semester.
Being the aim of this course mainly practical, theoretical and computer sessions will be alternated:
a) Theoretical sessions will consist on the exposition of the contents by the instructor. Students will be encouraged to participate by asking and answering short questions and solving exercises, so they keep their attention in the development of the lecture.
b) Computer sessions will be guided by the instructor. Students will be asked to look for data and make use of the provided software to carry out different statistical analyses by using those notions previously introduced during the lectures.
MiAulario will be used as the course web page.

Theoretical sessions will consist on the exposition of the contents by the instructor.
Students will be encouraged to participate and ask questions. The instructor will also propose exercises to be solved during the sessions. These exercises will be referred to real economic situations. (Proficiencies GP01, GP07, SP03, SP04.)
Computer sessions will be devoted to practical computing exercises. The instructor will provide the necessary guidelines so the students can individually perform different statistical analyses. Some of these assignments will be given back to the students so they can check their work. (Proficiencies GP01, GP05, GP07, GP17, SP03, SP04.)
Individual exercises will be proposed and also for small groups.
Students will be encouraged to attend to office hours (individually but also in small groups), not only to ask questions but for the instructor to check their progress. (Proficiencies GP01, GP02, GP03, GP06, GP07, GP09, GP14, GP17, SP03, SP04.)
|Learning outcome||Evaluation system||Weight (%)||Recoverable|
|LO1, LO2, LO3, LO5||Continuous evaluation: Individual in-term tests and problem solving sessions (individual or group work).||40%||No|
|LO1, LO2, LO3, LO4, LO5||Exam: Problem resolution and interpretation of outputs obtained with the statistical packages used during the semester.||60%||Yes|
It will be positively valued to have an active participation to the scheduled sessions.
An introduction to basic statistical concepts on data analysis, such as Descriptive Analysis of Univariate and Bivariate data real data, Description and Analysis of Temporal Data. Basic probability notions and an introduction to random variables.
Excel will be the usual framework for data analysis. Moreover students will be briefly introduced to the statistical package R Commander.
MiAulario will provide a communication channel between students and instructors.
