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 and Index numbers. 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.
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 and Index numbers. Basic notions of probability abd random variables are also introduced.
The use of different statistical packages will be fundamental in data analysis.
Course competencies:
c1) Apply appropriate descriptive techniques to problem resolution by using statistical software.
c2) Make a proper use of basic statistic concepts and notation and apply them to interpret numerical results.
c3) Develop efficient work habits.
From a total of 60 hours, 40 will be devoted to theoretical, problems 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 asked to participate by asking and answering short questions and solving exercises, so they keep their attention in the development of the lesson.
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 statistical analysis by using those notions previously introduced during the theoretical sessions.
MiAulario will be used as the course web page.
