single case study meaning

Single-case studies can provide a viable alternative to large group studies such as randomized clinical trials. Single case studies involve repeated measures, and manipulation of and independent variable. They can be designed to have strong internal validity for assessing causal relationships between interventions and outcomes, and external ...

Single case study analyses offer empirically-rich, context-specific, holistic accounts and contribute to both theory-building and, to a lesser extent, theory-testing. ... What this definition usefully captures is that case studies are intended - unlike more superficial and generalising methods - to provide a level of detail and ...

What is a case study? Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue.

Within a case study research, one may study a single case or multiple cases. Single case studies are most common in case study researches. Yin (2014, p. 59) says that single cases are 'eminently justifiable' under certain conditions: (a) when the case under study is unique or atypical, and hence, its study is revelatory, (b) when the case ...

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). The key commonality of these different case-oriented approaches is that ...

Abstract. This chapter addresses the peculiarities, characteristics, and major fallacies of single case research designs. A single case study research design is a collective term for an in-depth analysis of a small non-random sample. The focus on this design is on in-depth.

A single-case study is an in-depth analysis of a single case. This type of case study is useful when the researcher wants to understand a specific phenomenon in detail. For Example , A researcher might conduct a single-case study on a particular individual to understand their experiences with a particular health condition or a specific ...

Revised on November 20, 2023. A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research. A case study research design usually involves qualitative methods, but quantitative methods are ...

Although single case methods by definition focus on the level of the individual, there is also value in examining performance across multiple cases (a case series 46,47,48,49). Case series are ...

A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects. The methods used to study a case can rest within a quantitative, qualitative, or mixed-method investigative paradigm. ... Explain the Meaning ...

Studies that use a single-case design (SCD) measure outcomes for cases (such as a child or family) repeatedly during multiple phases of a study to determine the success of an intervention. The number of phases in the study will depend on the research questions, intervention, and outcome(s) of interest (see Types of SCDs on page 4 for examples).

Single case research typically requires a large amount of data since the justification of. using one case is often unusual access to a level of granular detail not permitted by multiple. cases. Researchers can generally collect three types of qualitative data: (1) interviews, (2) archival data, and (3) observations.

Case Study Definition. A case study is an in-depth investigation of a single person, group, event, or community. This research method involves intensively analyzing a subject to understand its complexity and context. The richness of a case study comes from its ability to capture detailed, qualitative data that can offer insights into a process ...

This study attempts to answer when to write a single case study and when to write a multiple case study. It will further answer the benefits and disadvantages with the different types. The literature review, which is based on secondary sources, is about case studies. Then the literature review is discussed and analysed to reach a conclusion ...

Researchers, economists, and others frequently use case studies to answer questions across a wide spectrum of disciplines, from analyzing decades of climate data for conservation efforts to developing new theoretical frameworks in psychology. Learn about the different types of case studies, their benefits, and examples of successful case studies.

Either single-case or multiple-case designs may be used in case study research. Single-case designs are usually appropriate where the case represents a critical case (it meets all the necessary conditions for testing a theory), where it is an extreme or unique case, where it is a revelatory case, or where the research is exploratory (Yin 1994 ...

Summary of Key Points: Single-case studies can provide a viable alternative to large group studies such as randomized clinical trials. Single-case studies involve repeated measures and manipulation of an independent variable. They can be designed to have strong internal validity for assessing causal relationships between interventions and outcomes, as well as external validity for ...

3.1.1 Format of a case study. Except to identify the case and the specific type of a case study that shall be implemented, the researchers have to consider if it's wisely to make a single case study, or if it's better to do a multiple case study, for the understanding of the phenomenon.

Case study can accommodate a variety of epistemological orientations, but these will influence research design . positivist: there is a single reality, independent of any observer ... Single case typologies p. 51 . critical: test whether the study's propositions are true under the circumstances specified (circumstances so clearly align with ...

An added benefit of this design, and all single-case designs, is the immediacy of the data. Instead of waiting until postintervention to take measures on the behavior, single-case research prescribes continuous data collection and visual monitoring of that data displayed graphically, allowing for immediate instructional decision-making.

Case study is a research methodology, typically seen in social and life sciences. There is no one definition of case study research.1 However, very simply… 'a case study can be defined as an intensive study about a person, a group of people or a unit, which is aimed to generalize over several units'.1 A case study has also been described as an intensive, systematic investigation of a ...

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in many different fields, including psychology, medicine, education, anthropology, political science, and social work.

The major advantage of multiple case research lies in cross-case analysis. A multiple case research design shifts the focus from understanding a single case to the differences and similarities between cases. Thus, it is not just conducting more (second, third, etc.) case studies. Rather, it is the next step in developing a theory about factors ...
