Module Leader
Principal Aims
This module allows the students to become familiar with the basic concepts of statistics, including graphical analysis and simple calculations conducted on the data. It is intended to provide the students with basic data analysis skills, to provide an introduction to conducting statistical analysis using advanced statistical package. as well as develop the foundations, necessary for the second year econometrics module.
Principal Learning Outcomes
:...acquire the tools of quantitative methods necessary to study core and optional first and second year modules in economics.
:...develop further their techniques of statistical methods and statistical modelling;
:...generate an awareness and analysis of data and of data handling through the use of statistical software.
