Need to analyse cause-effect relations across multiple cases and not sure how? Qualitative Comparative Analysis (QCA) offers a systematic, transparent, and innovative solution. This method is relevant for both quantitatively and qualitatively oriented researchers.

QCA, introduced by Charles Ragin in the 1980s and developed further since, is gaining prominence in various social sciences, including political science, economics and business, management, pedagogical sciences, health sciences, sociology, and environmental sciences.

Aims and working method

This is an introductory course. It is designed for people who have no or limited experience with QCA.

Participants will first have to watch (individually) a number of videos that were made for our Massive Open Online Course (MOOC) on QCA, which is offered on coursera.org. Participants should not follow our entire MOOC on Coursera first. Instead, the relevant videos will be provided by the lecturer to all participants in advance of the course.

The videos discuss the methodological foundations of QCA as well as how to conduct the method. After watching the videos, participants will meet offline to discuss questions and do exercises.

Please note that the offline class sessions comprise exercises that are also offered in our MOOC on Coursera. Thus the course will be less useful for participants who have already completed our MOOC on Coursera and done its exercises.

After completing the course, participants will know how:

  • QCA has historically developed and in which academic context;
  • a QCA study can be designed and under which conditions;
  • to conduct a QCA study by hand and (more conveniently) with the use of software;
  • to interpret and report the results.


  • QCA is relevant for researchers who normally work with qualitative methods and are looking for a more systematic way of comparing and assessing cases.
  • QCA is also useful for quantitative researchers who like to assess alternative (more complex) aspects of causation, such as how factors work together in producing an effect.
  • QCA can be used for the analysis of cases on all levels: macro (e.g. countries), meso (e.g. organizations) and micro (e.g. individuals).
  • QCA is mostly used for research of small- and medium-sized samples and populations (10-100 cases), but it can also be used for larger groups. Ideally, the number of cases is at least 10. QCA cannot be used if you are doing an in-depth study of one case.
