one that can test a particular theory. You can also talk to experienced case study researchers you know in your department or through your network, and look at relevant scholarly articles. This offers the possibility of several different layers of analysis which can reveal several different perspectives, with the added benefit of triangulation of the results. For example, a company or business could be the unit of analysis, and the object of the proposition be to examine company performance. Good case study design involves providing empirical data for analysis and conclusion (Gummesson, 2007), but doing so in such a way that stands up to scrutiny. 0000038432 00000 n In some cases, the online versions of these articles may contain supplementary documents on which the research was based, such as the protocol. The analysis of qualitative data is covered in the guide, "How to ... analyse qualitative data", which may provide some useful hints. The final screening of cases involves selecting the case(s) which best fit your design, where you can obtain the best data, and where you can obtain easy access to documents, people and other information. The latter is covered in part 3 of the author guide, "How to ... write a case study". Dul, J. and Hak, T. (2007), Case Study Methodology in Business Research, Butterworth-Heinemann, Oxford. Then, additional cases are examined to see if they contribute to the theory. 295-296) claim that the selection of cases has the same objectives as random sampling in that what is desired is a representative sample and useful variation on the dimensions of theoretical interest. Case studies are often seen as a "bolt-on" to a major research project, defining research questions or throwing further light on an issue that has been revealed by a survey. Each case is treated as a separate study, and the resulting data are compared. 851-876. Guidelines for writing the report, which may include a tentative outline. 1201) lists five rationales for single cases: The big advantage of multiple case studies is that evidence is provided from many sources, thus making it easier to generalise. A case study is an in-depth empirical investigation of a situation to understand and answer the how and why questions pertaining to a particular phenomenon.It refers to gathering information about a particular individual or a group in order to gain a holistic view about the subject of study .A case study approach is a holistic approach to observe the situation and gather valuable insights from the participants in the situation to explore phenomena. x�bb�f`b``Ń3� ���ţ�1�x4>F�c�a� ��� Next Page . Case study researchers are often advised to include more than one source of evidence, in order to facilitate triangulation and increase the richness and multifacetedness of their study. The beginning of the research process is all about definition: not only your research question, but also your unit of analysis, which is the actual object or entity being studied. One can ask themselves, "How do we prevent this from happening again?" The most common objection to case study research is that it is insufficiently rigorous. For example, a school might illustrate an important theoretical point, but if teachers and pupils refuse to engage and you can't gain access to classrooms, it will not be of much use. 0000020579 00000 n 0000011843 00000 n 3, pp. Yin (2009, location no. Examine rival explanations. observations & interviews). 52 No. While there are software packages available (for example, The Ethnograph, ATLAS.ti, HyperRESEARCH, and NVivo), these do not provide analysable outputs. (2008), "Case selection techniques in case study research: a menu of qualitative and quantitative options", Political Research Quarterly, Vol. Because visual communication precedes verbal, visual data collection methods are a powerful way of helping individuals retrieve unconscious thoughts. Especial care needs to be taken with vulnerable groups, such as children. Single cases and multiple cases can be holistic or embedded. 0000028246 00000 n 0000038218 00000 n Advertisements. Essay searching website. Besides discussing case study design, data collection, and analysis, the refresher addresses several key features of case study research. The research may also continue for an extended period of time, so processes and developments can be studied as they happen. This is known as analytical generalisation. This has been pointed out by a number of authors – Gerring and McDermott (2007), Lloyd-Jones (2003) and Yin (2009) – despite the fact that the case study is normally considered a qualitative method. Previous Page. 3, pp. 0000012413 00000 n Your initial literature review may have examined rival hypotheses, which can then be checked against the evidence. The objective of the case study is to analyse the linkage between data collection related to monitoring of energy savings and evaluation on energy efficiency policies. 0000028122 00000 n First, an abbreviated definition of a “case study” will help identify the circumstances when you might choose to use the case study method instead of (or as a complement to) some other research method. Furthermore, different data sources can support one another with complementary strengths: for example, document analysis is good for establishing facts, whereas interviews enable the researcher to probe. The use of multiple case designs has therefore become more frequent over recent years. External validity – the extent to which it is possible to generalise from the findings of case studies. This is different from quantitative analyses where these activities tend to occur more sequentially. Stake (1995) discussed two other potential sources of data for case study research: observation and document review. If there is a match, and the patterns coincide, then the initial proposition is confirmed, and the internal validity of the research is strengthened. Broadly speaking, the positivist approach looks at objective reality, which exists beyond the human mind, whereas the interpretivist approach sees knowledge of the world as inevitably affected by the observer. 0000001301 00000 n Methods can include interviewing, and observation, with the researcher concurrently recording his or her thoughts. 0000033228 00000 n Some case study research goes beyond being a type of qualitative research, by using a mix of quantitative and qualitative evidence. 0000032854 00000 n 1, pp. Construct validity can be improved by: 2. Data collection . However, given the difficulties of getting a representative case, on both practical and theoretical grounds, they suggest that purposive sampling may be more appropriate (p. 296). 1, pp. If data collection for case studies is difficult, data analysis is no less so. 0000017566 00000 n Hence it is typically used for exploratory research and data analysis. Providing inferential information, for example, about networks, which can be deduced from distribution lists etc. the opportunity for a holistic approach without the distraction of too many variables (Gummesson, 2007). In summary, the protocol should cover the following: You should have decided on the type of case, and type of design, and how your case(s) relate to the population studied, etc., at an earlier stage. What these methods have in common is the fact that they are designed to probe below the surface of what is being said, in other words to look at unconscious processes. 0000012692 00000 n Explanatory: the case study explores cause-effect relationships, and/or how events happen. Research methods: case study analysis . startxref However, with grounded theory design, the opposite happens: data are collected first of all, then theory developed, then more data are collected and compared with the theory, so the whole becomes an iterative process (see How to... implement grounded theory). Name: Course: Lecturer: Date: Introduction. For case study analysis, one of the most desirable techniques is to use a pattern-matching logic. Many would say that it is not, on the grounds that case studies are too particular (although this applies less to multiple case studies). Getting insight from such complicated information is a complicated process. x�b```b``sc`c`��� �� �@Q�[email protected]��p���)&)�9/��|�e�r�8��-���V1Y3e���pT�W��{�W��f�х�y{�,:�����c-"�y{��F�� ��d���ĩ�av�BV��y{]�b����;Y���������^��< P퇐4y�(����y:��� It is the investigation and exploration of an event thoroughly and deeply. The sources can include interviews, first-hand observation, surveys and document reviews. 749 49 This helped to enhance the reliability of this study. The case study database should contain plenty of evidence that is then referred to in the report. •In the collection of data we have to be systematic. 0000016307 00000 n "Data analysis is the process of bringing order, structure and meaning to the mass of collected data. Gerring, J. and McDermott, R. (2007), "An experimental template for case study research", American Journal of Political Science, Vol. endstream endobj 757 0 obj<> endobj 758 0 obj<>stream A large project with multiple cases, or a complex single case with much data collection, for example, may require a team of research assistants. For example, if someone has commissioned you to write a report, the format will be different to that for an academic journal. Yin, R.K. (2006), "Case study methods", in Green, J.L., Camilli, G. and Elmore, P.B. After the collection of data, there is a stage for reflection, which enables the researcher to update the initial conceptual framework on which the research was based. 0000011306 00000 n Case studies involve a detailed contextual analysis of a limited number of events or conditions and their relationships. Review methods: Literature examining qualitative data analysis was reviewed and strategies illustrated by the case study example provided. Case studies involve taking a close look at a particular case – an individual, a group of individuals, or an organization. You need a case where people will be helpful, leading you to key informants, providing access to documents, and allowing you to interview or survey staff. Notes, from interviews, observation, document analysis, etc. ���_��W�+��� Qiannan Zhang, Tian Huang, Yongxin Zhu, and Meikang Qiu . While it offers depth and specificity, case study research also offers breadth and diversity in terms of methods of data collection and analytical techniques. Data collection methods in a case study may involve interviews, observations, questionnaires, checklists, analysis of recorded data and opinionnaires. Almost every year a hurricane blast through Florida and takes its toll on the business, industry and affects the lives and dollars of the company and its workers. 51 No. Both apply in case study research.
