OBIETTIVI FORMATIVI

The teaching provides the students with the basic notions of the statistical methods useful for the study of political science and international relations. The students will be able to produce statistical reports with data tables, graphs and more complex analyses such as multiple regression. The teaching has an application-oriented approach, and several hours will be devoted to the introduction to data analysis software such as Microsoft Excel and IBM SPSS".

OBIETTIVI FORMATIVI (DETTAGLIO) E RISULTATI DI APPRENDIMENTO

• Knowledge and understanding Students acquire adequate knowledge of the principles of measuring and statistically analysing political phenomena. Students are able to import data into statistical analysis software, produce tabular and graphical representations, summarize them using the main descriptive statistics and analyze the relationship between two or more variables.
• Ability to apply knowledge and understanding Students are able to find the data necessary to understand the political phenomena and to replicate the indices studied during the course on new data or to build new ones, also in a historical perspective and international comparison.
• Autonomy of judgement Students are able to assess the quality of data and the quality of the research reports available online.
• Communication skills Students acquire the fundamental statistical vocabulary to communicate clearly and unambiguously with specialist and non-specialist interlocutors. In particular, they learn to interpret data tables and graphic representations typical of the economic, social and political sciences, especially when produced by official statistical bodies.
• Learning skills Students, having had the opportunity to know in detail many official surveys, are able to assess the quality of the data they will use during their studies and professional career.
