Qualitative Comparative Analysis (Patrick A. Mello)
Methods Course at the 20th Swiss Social Science Summer School
Università della Svizzera Italiana, Lugano, 22-26 August 2016
The workshop 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 [Read Further]
