How can scholars select cases from a large universe for in-depth case study analysis? Random sampling is not typically a viable approach when the total number of cases to be selected is small. Hence attention to purposive modes of sampling is needed. Yet, while the existing qualitative literature on case selection offers a wide range of suggestions for case selection, most techniques discussed require in-depth familiarity of each case. Seven case selection procedures are considered, each of…

Selecting Cases for Intensive Analysis

This study revisits the task of case selection in case study research, proposing a new typology of strategies that is explicit, disaggregated, and relatively comprehensive, and arguing that medium-n samples occupy an unstable methodological position.

A Careful Look at Modern Case Selection Methods

It is argued that a number of common case selection strategies work well only in idiosyncratic situations and should be abandoned in favor of the more powerful and robust case selection methods that this analytical framework identifies.

The Case for Selecting Cases That Are Deviant or Extreme on the Independent Variable

Qualitative and multimethod scholars face a wide and often confusing array of alternatives for case selection using the results of a prior regression analysis. Methodologists have recommended

Case study research requires researchers to purposefully select information-rich cases, as they will allow researchers an in-depth understanding of relevant and critical issues under investigation

A Bayesian Perspective on Case Selection

This paper presents a far simpler Bayesian perspective on case selection, where the single overarching principle is to maximize information that will help develop, refine, and/or compare hypotheses.

Three Pathways to Case Selection in IB: A Twenty–Year Review, Analysis & Synthesis

With its focus on locational context, International Business (IB) is a prime candidate for the application of Case Study (CS) methodology. Yet many IB scholars still have doubts about CSs, possibly

Is There a (Viable) Crucial-Case Method?

Case study researchers use diverse methods to select their cases, a matter that has elicited considerable comment and no little consternation. Of all these methods, perhaps the most controversial is

Paired Comparison and Theory Development: Considerations for Case Selection

ABSTRACT Despite the widespread use of paired comparisons, we lack clear guidance about how to use this research strategy in practice, particularly in case selection. The literature tends to assume

Case Selection via Matching

Through several applications, it is shown that matching methods have advantages over traditional selection in “most similar” case designs: they ensure that most similar cases are in fact most similar; they make scope conditions, assumptions, and measurement explicit; and they make case selection transparent and replicable.

Single-Outcome Studies

Most methodological work on case studies understands this topic as a study of a case where the objective is to discover something about a broader population of cases. Yet, many case studies

This paper aims to clarify the meaning, and explain the utility, of the case study method, a method often practiced but little understood. A “case study,” I argue, is best defined as an intensive

The Possibility Principle: Choosing Negative Cases in Comparative Research

A central challenge in qualitative research is selecting the “negative” cases (e.g., nonrevolutions, nonwars) to be included in analyses that seek to explain positive outcomes of interest (e.g.,

Making the Most of a Case Study: Theories of the Welfare State and the American Experience

Although the reputation of case studies has recently been on the rise in social science, they face a number of analytical obstacles. The questions asked in case studies are often thought to have

Nested Analysis as a Mixed-Method Strategy for Comparative Research

A unified approach which joins intensive case-study analysis with statistical analysis improves the prospects of making valid causal inferences in cross-national and other forms of comparative research by drawing on the distinct strengths of two important approaches.

Evidence and Inference in the Comparative Case StudyEvidence and Inference in the Comparative Case Study

By concentrating on the logic of testing necessary conditions, this paper attempts to show that the methodological implications of selecting on the dependent variable are much less threatening to the validity of small-n comparative case study work than has often been claimed.

An Experimental Template for Case Study Research

Methods are usually classified as either “experimental” or “observational,” a dichotomy that has governed social science research for centuries. By implication, this dichotomization precludes a

Mill's “method of agreement” is presented as an alternative method of comparison, a method that not only can and has been used quite effectively with survey research in comparative politics, but one that is completely free from the methodological short-comings attributed to it.
