    Qualitative Comparative Analysis (QCA)

    Methods Course at the 23rd Swiss Summer School in Social Science Methods

    From August 19-23, 2019 I taught a one-week intensive course on Qualitative Comparative Analysis (QCA), organized by FORS, the Swiss Foundation for Social Science Research and the Università della Svizzera Italiana in beautiful Lugano, Switzerland. The course drew on my textbook Qualitative Comparative Analysis: Research Design and Application, under contract with Georgetown University Press. From the course description: “The course provides participants with a thorough introduction to Qualitative Comparative Analysis (QCA), both as a research approach and as a data analysis technique. In recent years, this set-theoretic method has gained recognition among social scientists as a methodological approach that holds specific benefits for comparative studies. The course begins by familiarizing participants with the foundations of set theory and the basic concepts of the methodological approach of QCA, including necessary and sufficient conditions, Boolean algebra, and fuzzy logic. The next step is devoted to the calibration of empirical data into crisp and fuzzy sets. Once these essentials are in place, the course moves on to the construction and analysis of truth tables as the core of the QCA procedure. Here, we will also spend time to discuss typical challenges that arise during a truth table analysis, and techniques to overcome such problems. Finally, the course will introduce consistency and coverage as parameters of fit, as well as additional measures to assess the robustness of QCA results.”

    Besides the technical introduction of QCA and its variants, the course will provide opportunities to discuss general aspects of comparative research design, including criteria for concept building and case selection, and data-related issues. Participants will be given the opportunity to present their own work and to receive individual feedback on their projects. Throughout the course, participants will conduct set-theoretic analyses within the R software environment (packages “QCA” and “SetMethods”). The software will be introduced on the first day and used for exercises and examples throughout the course, so that participants gain a level of proficiency that enables them to conduct their own QCA analyses upon the completion of the course. Participants are encouraged to bring their own qualitative and/or quantitative data for course exercises (if available, preliminary data is fine). In addition, datasets from published studies will be made available and used for in-course exercises.”

    Qualitative Comparative Analysis and Fuzzy Sets

    Patrick A. Mello (Week 1), Carsten Q. Schneider (Week 2), and Nena Oana (Teaching Assistant)

    Methods Course taught for the European Consortium for Political Research at Central European University, Budapest, 27 July – 7 August 2017

    Course Outline: “This course introduces participants to set-theoretic methods and their application in the social sciences with a focus on Qualitative Comparative Analysis. The introductory course is complemented by an advanced course that is taught at the ECPR Winter School in Bamberg. The course starts out by familiarizing students with the basic concepts of the underlying methodological perspective, among them the central notions of necessity and sufficiency, formal logic and Boolean algebra. From there, we move to the logic and analysis of truth tables and discuss the most important problems that emerge when this analytical tool is used for exploring social science data. Right from the beginning, students will be exposed to performing set-theoretic analyses with the relevant R software packages. When discussing set-theoretic methods, in-class debates will engage on broad, general comparative social research issues, such as case selection principles, concept formation, questions of data aggregation and the treatment of causally relevant notions of time. Examples are drawn from published applications in the social sciences. Participants are encouraged to bring their own raw data for in-class exercises and assignments, if available“ [Read Further]
