Yin case study research design and methods

Yes If research focusses on what questions, either of two positions arises. They are advantageous when the research goal is to describe the prevalence of a certain phenomenon or to be predictive of a certain outcome. The key is to understand that your research questions have both substance — for example what is my study about and form for example am I asking a who, what, where, why or how question.

Case Study Research

Histories are preferred when there is virtually no access or control, and can of course be done about contemporary events: Experiments are done when an investigator can manipulate behavior directly, precisely and systematically.

The case study is preferred in examining contemporary events, but when the relevant behaviors can not be manipulated.

Perhaps the greatest concern has been the lack of rigor of case study research. To many times,the case study researcher has been sloppy, has not followed systematically procedures, or has allowed equivocal evidence or biased views to influence the directions of the findings of the conclusions. A second concern is that they provide little basis for scientific generalization. The short answer is that case studies, like experiments, are generalizable to theoretical propositions and not to populations or universes.

A third concern is that case studies take to long. This incorrectly confuses the case study method with a specific method of data collection, such as ethnography or participant observation. Case studies are a form of inquiry that does not depend solely on ethnographic or participant observer data. You could even do a high level case study without leaving the telephone or the internet.

Case study research : design and methods

Overlooked has been the possibility that case studies can offer important evidence to complement experiments. Different kind of case studies but a common definition The essence of a case study, the central tendency among all types of case study, is that it tries to illuminate a decision or set of decisions: In other words you use the case study method because you want to understand a real-life phenomenon in depth, but such understanding encompasses important contextual conditions — because they were highly pertinent to your phenomenon of study e.

Because phenomenon and context are not always distinguishable in real life situations, other technical characteristics, including data collection and data analysis strategies, become the second part of our technical definition of case studies: The case study inquiry: Case studies include both single and multiple-case studies. Some case study research goes beyond being a type of qualitative research, by using a mix of quantitative and qualitative evidence.

Case studies have a distinctive place in evaluation research. Also case studies can be conducted and written with many different motives.


These motives vary from the simple presentation of individual cases to desire to arrive at broad generalizations based on case study evidence but without presenting any of the case studies separately.

Designing Case Studies The next task is to design your case study. For this purpose you need a plan or research design. The case study is a separate research method that has its own research design. A research design is a logical plan for getting from here to there, where here may be defined as the initial set of questions to be answered and there is some set of conclusions answers about these questions.

A research plan guides the investigator in the process of collecting, analyzing and interpreting observations.
