The course provides a general introduction to the design of empirical social science research. Following a summary of the basic features of the scientific method, the course addresses the different phases of the social research process. We begin by discussing how to choose, state, and justify the research problem, from which specific research questions are subsequently derived. Second, we consider the definition of the conceptual framework for the research, focusing on the notions of theory, hypothesis, and model. Third, we present strategies for evaluating, organizing, and synthesizing the literature related to the research problem. Then, attention is devoted to three major tasks: definition of the units of analysis, identification of the target and study populations, and choice of sampling design. Finally, we examine uses, strengths and limitations of various types of research design. Upon course completion, students should be able to design their own empirical research, and to write the corresponding research proposal.
