What is the difference between single case study and multiple case study?
Subsequently, one may also ask, what is a single case study?
The single case study is the most basic form of case-oriented research, but researchers may also conduct a series of case studies, each study building on the previous, or conduct simultaneous studies of several instances of the same phenomenon (as in comparative research).
Secondly, what is a multiple case study?
Multiple-case design, or collective case design, refers to case study research in which several instrumental bounded cases are selected to develop a more in-depth understanding of the phenomena than a single case can provide.
Case studies are in-depth investigations of a single person, group, event or community. Typically, data are gathered from a variety of sources and by using several different methods (e.g. observations & interviews). In psychology, case studies are often confined to the study of a particular individual.
