Anotace
This graduate course assumes no prior knowledge of statistics or knowledge of mathematics beyond
GCSE (or equivalent)-level. It provides a basic introduction to statistics essential for multi-disciplinary study. The emphasis is on elements of statistical thinking and insight is drawn from simple data and concepts rather than complex derivations and formulae. The course presents quantitative methods as an essential intellectual method appropriate for study alongside other approaches to social sciences.
The course is oriented towards making practical use of simple statistical methods and is focused particularly on interpretation of the results. The second half of the course, introduces students to regression analysis and so prepares them for more advanced courses in quantitative methods and econometrics. By the end of the course students all students will be able to produce and interpret empirical results using real world data. The course uses the STATA software package.
