QUALITATIVE COMPARATIVE ANALYSIS (QCA) Issued by Intrac
Qualitative Comparative Analysis (QCA) is a methodology that enables the analysis of multiple cases in complex situations. It can help explain why change happens in some cases but not others. QCA is designed for use with an intermediate number of cases, typically between 10 and 50. It can be used in situations where there are too few cases to apply conventional statistical analysis.
