The purpose of this course is to provide training on all aspects that enable a researcher to build and implement the most appropriate comparative research design – the latter broadly defined as any research enterprise that comprises at least two ‘cases’ or observations. On the one hand, the course will cover a few fundamental upstream … Continue reading Comparative Research Designs →

This is a methodological course on set-theoretic methods for the social sciences. While the spectrum of set-theoretic methods is broad, including techniques such as Mill’s methods or typological theory, this course primarily focuses on Qualitative Comparative Analysis (QCA). Invented by Charles Ragin , this technique is still undergoing modifications, improvements, and ramifications with applications in … Continue reading Qualitative Comparative Analysis (QCA): Performing Basic and Advanced Analyses using R →

This is a methodological course on set-theoretic methods for the social sciences. While the spectrum of a set-theoretic methods is broad, including techniques such as Mill’s methods or typological theory, this course primarily focuses on the crisp-set and fuzzy-set versions ofQualitative Comparative Analysis (QCA). Invented by Charles Ragin , this technique isstill undergoing modifications, improvements, … Continue reading Qualitative Comparative Analysis (QCA): Performing Basics and Advanced Analyses using R →

This doctoral course will teach you the fundamentals of Necessary Condition Analysis (NCA) and help you design your first NCA research project. Necessary Condition Analysis is an innovative research method for identifying necessary (but not sufficient) conditions in data sets. Allowing you to separate the "need-to-haves" from the "nice-to-haves", NCA offers compelling practical advice and … Continue reading ​​Introduction to Necessary Condition Analysis (NCA)​ →

At this year's ICPSR Summer Program, Professor Ingo Rohlfing will offer an introductory QCA course (virtual/remote) from July 24 to 28. The course introduces participants to the complete QCA workflow and its implementation in RStudio. The course is virtual with a combination of live sessions and recordings for asynchronous following. Here is the course outline: … Continue reading Qualitative Comparative Analysis Training →

The PDW includes 3 Parts. If you have no or only a little knowledge of, and experience with, QCA you can join us during Part 1 to learn the basic “nuts and bolts” of QCA and configurational logic and understand if this might be the right tool for your research project. If you’re joining us … Continue reading Qualitative Comparative Analysis (QCA): A Set-Analytic Approach To Studying Configurations →

This workshop provides participants with a thorough introduction to Qualitative Comparative Analysis (QCA). Since its inception (Ragin 1987), QCA has gained recognition among social scientists as a case-based research method that is ideally suited to capture causal complexity. This essentially describes a situation where an outcome results from multiple pathways and different combinations of conditions. … Continue reading Qualitative Comparative Analysis (QCA) →

Based on formal logic, set theory and Boolean algebra, Qualitative Comparative Analysis (QCA) is a research method used to analyse combinations of conditions which are sufficient and/or necessary for the outcome under study. Developed by the political scientist and sociologist Charles Ragin, QCA focuses holistically on cases as combinations of factors rather than on the … Continue reading Tübingen Methods Center Fall School, Qualitative Comparative Analysis Workshop →

The International QCA Paper Development Workshop (PDW) 2023 provides a unique platform for researchers working on papers involving QCA to meet QCA experts, get feedback on their on-going research and learn about the latest methodological developments in QCA. The workshop is interdisciplinary and interactive and allows for in-depth discussions and individual feedback from internationally-renowned QCA … Continue reading International QCA Paper Development Workshop 2023 →
