Case Study Research Design
Martyn Shuttleworth 738K reads
The case study research design have evolved over the past few years as a useful
tool for investigating trends and speci�c situations in many scienti�c 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.

What is a Case Study?
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 �eld 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 scienti�c 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, anthropologists 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 speci�c cases and ensure a more holistic
approach to research.

The Argument for and Against the Case Study Research
Design
Some argue that because a case study is such a narrow �eld that its results cannot be extrapolated to
�t an entire question and 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.
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 �exibility. Whilst a pure scientist is
trying to prove or disprove a hypothesis, a 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, anthropology and ecology they are an essential
tool. It is important to ensure that you realize that a case study cannot be generalized to �t 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 statistical 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.
How to Design and Conduct a Case Study
The advantage of the case study research design is that you can focus on speci�c and interesting
cases. This may be an attempt to test a theory with a typical case or it can be a speci�c topic that is of
interest. Research should be thorough and note taking should be meticulous and systematic.
The �rst foundation of the case study is the subject and relevance. 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. A
case study on one or two speci�c countries becomes a powerful and focused 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 scienti�c report, there is no strict set of rules
so the most important part is making sure that the study is focused and concise; 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 survey, it 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.
How to Analyze the Results
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 scienti�c study which deals with facts, a case study is based on opinion and is very
much designed to provoke reasoned debate. There really is no right or wrong answer in a case study.
