Case Study Research Design - How to conduct a Case Study

 

case study design

Design of case study Since case study method receives criticism in terms of its lack of robustness as a research tool, crafting the design of case studies is of paramount importance. Researchers can adopt either a single-case or multiple-case design depending on the issue in question. In cases where there. In a retrospective study, the distribution of the disease outcomes (i.e. how many are ill, who is ill, how ill they are etc.) is known at the beginning of the study period. By comparison, case-control studies take a representative group of subjects, and consider known outcomes in that group, and will, by dint of study design, and careful choice. case study design an investigation strategy involving extensive exploration of a single unit of study, which may be a person, family, group, community, or institution, or a very small number of subjects who are examined intensively. The number of variables is usually very large.


FEM - Case to case study design


The case study research design have evolved over the past few years as a useful tool for investigating trends and specific situations in many scientific disciplines. The case study has been especially used in social science, psychology, anthropology and ecology. This method of study is especially useful for trying to test theoretical models by using them in real world situations. For example, if an anthropologist were to live amongst a remote tribe, whilst their observations might produce no quantitative data, they are still useful to science.

Basically, a case study is an in depth study of a particular situation rather than a sweeping statistical survey. It is a method used to narrow down a very broad field of research into one easily researchable topic. Whilst it will not answer a question completely, it will give some indications and allow further elaboration and hypothesis creation on a subject. The case study research design is also useful for testing whether scientific theories and models actually work in the real world.

You may come out with a great computer model for describing how the ecosystem of a rock pool works but it is only by trying it out on a real life pool that you can see if it is a realistic simulation. For psychologists, case study design and social scientists they have been regarded as a valid method of research for many years. Scientists are sometimes guilty of becoming bogged down in the general picture and it is sometimes important to understand specific cases and ensure a more holistic approach to research.

Some argue that because a case study is such a narrow field that case study design results cannot be extrapolated to fit an entire question case study design that they show only one narrow example. On the other hand, it is argued that a case study provides more realistic responses than a purely statistical survey. The truth probably lies between the two and it is probably best to try and synergize the two approaches.

It is valid to conduct case studies but they should be tied in with more general statistical processes, case study design. For example, a statistical survey might show how much time people spend talking on mobile phones, but it is case studies of a narrow group that will determine why this is so.

The other main thing to remember during case studies is their flexibility. Whilst a pure scientist is trying to prove or disprove a hypothesisa case study might introduce new and unexpected results during its course, and lead to research taking new directions.

The argument between case study and statistical method also appears to be one of scale. Whilst many 'physical' scientists avoid case studies, for psychology, case study design, anthropology and ecology they are an essential tool. It is important to ensure that you realize that a case study cannot be generalized to fit a whole population or ecosystem. Finally, one peripheral point is that, when informing others of your results, case studies make more interesting topics than purely case study design surveys, something that has been realized by teachers and magazine editors for many years.

The general public has little interest in pages of statistical calculations but some well placed case studies can have a strong impact. The advantage of the case study research design is that you can focus on specific and interesting cases.

This may be an attempt to test a theory with a case study design case or it can be a specific topic that is of interest. Research should be thorough and note taking should be meticulous and systematic.

The first foundation of the case study is the subject and relevance, case study design. In a case study, you are deliberately trying to isolate a small study group, one individual case or one particular population. For example, statistical analysis may have shown that birthrates in African countries are increasing, case study design. A case study on one or two specific countries becomes a powerful and case study design tool for determining the social and economic pressures driving this.

In the design of a case study, it is important to plan and design how you are going to address the study and make sure that all collected data is relevant.

Unlike a scientific report, case study design, there is no strict set of rules so the most important part is making sure that the study is focused and case study design otherwise you will end up having to wade through a lot of irrelevant information. It is best if you make yourself a short list of 4 or 5 bullet points that you are going to try and address during the study.

If you make sure that all research refers back to these then you will not be far wrong. With a case study, even more than a questionnaire or surveyit is important to be passive in your research. You are much more of an observer than an experimenter and you must remember that, even in a multi-subject case, each case must be treated individually and then cross case conclusions can be drawn.

Analyzing results for a case study tends to be more opinion based than statistical methods. The usual idea is to try and collate your data into a manageable form and construct a narrative around it.

Use examples in your narrative whilst keeping things concise and interesting. It is useful to show some numerical data but remember that you are only trying to judge trends and not analyze every last piece of data. Constantly refer back to your bullet points so that you do not lose focus. It is always a good idea to assume that a person reading your research may not possess a lot of knowledge of the subject so try to write accordingly.

In addition, unlike a scientific study which deals with facts, a case study is based on opinion and is very case study design designed to provoke reasoned debate. There really is no right or wrong answer in a case study.

Dec 29,  · Case Study Design: Definition, Advantages & Disadvantages. Mel is putting together a case study, or detailed analysis of a single person or group and its relationship to a phenomenon. For. Case to case studies may be a convenient design when information is available for the sub class of cases used as controls. However, as in any case control study, investigators need to be very cautious and verify that exposure in the control group reflects accurately exposure in the source population for cases. case study design an investigation strategy involving extensive exploration of a single unit of study, which may be a person, family, group, community, or institution, or a very small number of subjects who are examined intensively. The number of variables is usually very large.
