Tools to collect data can include surveys, interviews, documentation review, observation, and even the collection of physical artifacts.
Post-positivism is evident in how he defines "case study as a form of empirical inquiry" p. Researchers who have contributed to the development of case study research come from diverse disciplines and their philosophical underpinnings have created variety and diversity in approaches used.
Evaluate and Analyze the Data The researcher examines raw data using many interpretations in order to find linkages between the research object and the outcomes with reference to the original research questions.
For STAKEto understand the case "requires experiencing the activity of the case as it occurs in its context and in its particular situation" p. Crossovers need even less--one-quarter of the number for an equivalent trial with a control group--because every subject gets the experimental treatment.
Case study research generally answers one or more questions which begin with "how" or "why. Because of this, constructivism and interpretivism commonly permeate the implementation of this research design.
Use, appraisal, and research: The researcher may enter some data into a database and physically store other data, but the researcher documents, classifies, and cross-references all evidence so that it can be efficiently recalled for sorting and examination over the course of the study.
Case studies in business[ edit ] At Harvard Law School InChristopher Langdell departed from the traditional lecture-and-notes approach to teaching contract law and began using cases pled before courts as the basis for class discussions.
Investigators must also be aware that they are going into the world of real human beings who may be threatened or unsure of what the case study will bring.
Selection of cases is based on the purpose of the research and related to the theoretical propositions about the topic of interest.
Of the organizations, 9 were small employees or less48 were mid-sizedemployeesand 17 were large more than 20, employees. For experimental designs, a pilot study can consist of the first 10 or so observations of a larger study. The continued use of case study to understand the complexities of institutions, practices, processes, and relations in politics, has demonstrated the utility of case study for researching complex issues, and testing causal mechanisms that can be applied across varied disciplines.
The report also includes confirming and conflicting findings from literature reviews. Like YINMERRIAMasserts that when information is plentiful and concepts abstract, it is important to utilize processes that help interpret, sort, and manage information and that adapt findings to convey clarity and applicability to the results.
STAKEan educational psychologist with an interest in developing program evaluation methods, used a constructivist orientation to case study. They will have to gather information that may help them in solving such issues. The ROI is immense; we find that employees waste inordinate amounts of time being lost on intranets.
Applicability to Library and Information Science Case study research, with its applicability across many disciplines, is an appropriate methodology to use in library studies. While having a disciplined approach to the process and acknowledging that case study can use quantitative methods, STAKE's approach is underpinned by a strong motivation for discovering meaning and understanding of experiences in context.
Precision, process, and practicality are core attributes of YIN's approach to case study. Researchers could use the case study method to further study the role of the librarian in implementing specific models of service. For example, if you are interested in enhancing sprint performance, your dependent variable or outcome variable is automatically some measure of sprint performance.
Random and large samples were at no time part of the picture. The primary pitfall of this type of study is that initial findings may seem convincing enough to be released prematurely as conclusions.Case Studies: Types, Designs, and Logics of Inference JACK S.
LEVY Department of Political Science Rutgers University New Brunswick A deviant case study is a research design or case selection technique for the purpose of reﬁning or replacing an existing theory or hypothesis, and thus.
Case study research is the most popular research method for researchers in industrial marketing. However despite a number of attempts the problem of satisfactorily justifying the use of case research.
An overview of the types of case study designs is provided along with general recommendations for writing the research questions, developing propositions, determining the “case” under study, binding the case and a discussion of. The design is the structure of any scientific work.
It gives direction and systematizes the research. Different types of research designs have different advantages and disadvantages.
The researcher investigates the object of the case study in depth using a variety of data gathering methods to produce evidence that leads to understanding of the case and answers the research questions.
The specific format for a case study can vary greatly. In some instances, your case study will focus solely on the individual of interest.
Other possible requirements include citing relevant research and background information on a particular topic.Download
