In single case studies, all cases do not have literature reviews but many of them have instead a title like “Case study” or “Case description”. In multiple cases
all have a conclusion
and the most of them have some sort of literature review but not all of them.
What is multiple-case study with example?
Multiple-case design is a
research methodology in which several instrumental, bounded cases are examined using multiple data collection methods
. This research methodology is more powerful than single-case designs as it provides more extensive descriptions and explanations of the phenomenon or issue.
What is the difference between single case study and multiple-case study?
In single case studies, all cases do not have literature reviews but many of them have instead a title like “Case study” or “Case description”. In multiple cases
all have a conclusion
and the most of them have some sort of literature review but not all of them.
How many cases in a multiple-case study?
Typically, a case study has a sample of one (i.e., the bounded case, but note that sam- pling can also occur within the case), unless the research project is a multiple-case study. In a multiple-case study, having
three to four distinct cases for comparison
is probably the most cases that one can realistically handle.
What is a multi-site case study?
A multi-site case study
investigates a contemporary phenomenon found in two or more real-world or naturalistic settings
. … A multi-site case study is a potentially useful means of capturing the complexity of a phenomenon while revealing rich understandings about the context in which it is based.
Why do a single case study?
When rigorously designed, single-case studies can be
particularly useful experimental designs
in a variety of situations, even when researcher resources are limited, studied conditions have low incidences, or when examining effects of novel or expensive interventions.
What are the types of case study?
- Collective case studies: These involve studying a group of individuals. …
- Descriptive case studies: These involve starting with a descriptive theory. …
- Explanatory case studies: These are often used to do causal investigations.
What is a within case study?
Within-case analysis in case study research is
the in-depth exploration of a single case as a stand-alone entity
. … This allows the researcher to understand the intrinsic aspects of a case study that are representative of other cases or because it is unique in its attributes.
What is a qualitative case study?
The qualitative case study is
a research method which enables a complex phenomenon to be explored through the identification of different factors interacting with each other
. The case observed is a real situation. In the field of nursing science, it may be a clinical decision-making process.
What is a collective case study?
Collective case study
involves more than one case
, which may or may not be physically colocated with other cases. A collective case study may be conducted at one site (e.g., a school, hospital, or university) by examining a number of different departments or other units at that one site.
What is the minimum sample size for case study?
Some say
between 30-50 sample size
is fine, while others say between 5-25, and another group say between 5-12. There is even a renowned authority who claimed that one participant is enough depending on what a researcher is researching.
What is Yin’s recommended sample size for a case study?
Five
is the maximum sample size for case reports: statistical justification, epidemiologic rationale, and clinical importance.
What is a good sample size for a qualitative case study?
This gives a range of what sample size they would consider appropriate, and later in the same paper, they recommend a range of 20-30 interviews for grounded research and
15-30 interviews for case studies
.
What are the boundaries of a case study?
Case studies are often focused on entities that
have relatively clearly defined spatial boundaries
as they are experienced and conceptualized in everyday life, such as the borders of states or the walls bounding prisons or schools. Such organizational boundaries are often clearly marked, monitored, and managed.
What are the strengths of case study?
- Provides detailed (rich qualitative) information.
- Provides insight for further research.
- Permitting investigation of otherwise impractical (or unethical) situations.
Is a single case study qualitative or quantitative?
It is also important to distinguish single-subject research from case studies. A case study is a detailed description of an individual, which can include
both qualitative and quantitative analyses
. (Case studies that include only qualitative analyses can be considered a type of qualitative research.)
