Eleven school building administrators were interviewed to provide insight into the research questions. The case study research design is also useful for testing whether scientific theories and models actually work in the real world. To begin to reduce the tensions among idiographic and nomothetic research traditions, case study researchers must recall their original goals for the cross-case analysis. Multiple Case Study In: The SAGE Encyclopedia of Social Science Research Methods. The case study is the comprehensive study of one or very few research subjects, allowing obtaining a broad and detailed knowledge of the latter. When the approach is applied correctly, it becomes a valuable method for health science research to develop theory, evaluate programs, and develop interventions. "Case study research is a qualitative approach in which the investigator explores a bounded system (a case) or multiple bounded systems (cases) over time through detailed, in-depth data collection involving multiple sources of information (e.g., observations, interviews, audiovisual material, and documents and reports) and reports a case description and case-based themes" (ibid. It can be used in both quantitative and qualitative studies. A case study research design usually involves qualitative methods, but quantitative methods are sometimes also used. REBECA RENATA CLASS. Methods: A case centred on a patient with lung cancer. The matrix then shows that single- and multiple-case studies reflect different design situations and that, within these two variant, there also can be unitary or multiple units of analysis. The objective of this paper is to discuss the specificity of multiple case study (MCS) research design using analysis of research description realized according to this strategy in the field of place branding and place marketing published between 1976 and 2016 in scholarly journals. However, much can be learned from a particular case. Case study designs tend to not be as laborious and time consuming as ethnography or grounded theory, and they are robust enough to help researchers address many different types of research questions. It is a method-appropriate strategy of founding the credibility of qualitative analyses. Case study evaluations are valuable where broad, complex questions have to be addressed in complex circumstances. (Stake, 2005). Data were In qualitative research, the context informs the research question. A search to determine what is known about the case(s) is typically conducted. with open-ended questions or descriptions of what you observe). 3. ... in surveys, observations or case studies, your data can be represented as numbers (e.g. This study attempts to answer when to write a single case study and when to write a multiple case study. By placing greater emphasis on your documents and archival records, you may better confirm the findings from the interview transcripts. It will further answer the benefits and disadvantages with the different types. The steps when using case study methodology are the same as for other types of research.6 The first step is defining the single case or identifying a group of similar cases that can then be incorporated into a multiple-case study. Qualitative research methods are ways of investigating a topic to gain a deeper understanding and generate new theories and ideas. Why Use Multiple Sources of Evidence. Perhaps because a case study focuses on a single unit, a single instance, the issue of generalizability looms larger here than with other types of qualitative research. Because of different reasons the case studies can be either single or multiple. using rating scales or counting frequencies) or as words (e.g. ). Creswell describes the qualitative approach to a case study with the investigator focusing on one or more cases over time through detailed, in-depth data collection involving multiple sources of information (Creswell 2013). Seven cases were recruited, which included 12 companions. Within the case were the patients, the health professionals they consulted with and accompanying companions. The use of multiple case designs has therefore become more frequent over recent years. To do a case study in qualitative research, carefully select a specific subject and use appropriate data collection methods and analysis to attempt to understand the subject and surrounding circumstances -- also called context.
