Data Analysis

The course aims to provide students with a solid foundation in applied statistical methodology. Students who attend and complete the course will master the basic toolkit of quantitative research (i.e. cases, types of variables, datasets, hypotheses testing); will achieve an understanding of why sampling is used, different sampling methods and how to make predictions (inference) in the social sciences; they will be proficient with the main tools for univariate and bivariate analyses. Students will also receive basic training on the use of the statistical software Stata and, by the end of the course, they will be able to produce basic statistical analyses of quantitative data independently. SPSS and Excel will also be introduced.
