# POL40950 Introduction to Statistics

Introduction to the use of data for statistical analysis in political science and related disciplines (sociology, public policy, international relations, etc.). The module will introduce concepts such as measurement, variables, statistical data, and provide an introduction to basic descriptive statistics summarizing numerical data, both graphically and numerically. The core of the module will be an introduction to applied multiple regression analysis, discussing the purpose, implementation, and interpretation of standard regression models, for both continuous and dichotomous variables. It will introduce the basics of statistical inference, drawing conclusions about populations on the basis of sample data, and apply this to the regression context. Practical R programming skills for political science research are taught, strengthening analytical robustness through addressing assumptions, estimation, and inference in linear regression.

Approaches to Teaching and Learning:
Each week's sessions include lectures and labs. The lectures center on key aspects of statistical inference and their interpretation, supported by examples. Small group exercises are integrated into lectures for direct engagement with examples. In lab sessions, students receive clear instructions and address problems involving data manipulation, visualization, and statistical techniques using R. The homework assignments are structured so that they gradually lead up to a comprehensive regression analysis and associated social science paper, putting the technical material of the class in practice.
