What Is a Case Study? | Definition, Examples & Methods
Published on May 8, 2019 by Shona McCombes. Revised on July 21, 2022.
A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.
A case study research design usually involves qualitative methods, but quantitative methods are sometimes also used. Case studies are good for describing, comparing, evaluating and understanding different aspects of a research problem.

When to do a case study
A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.
Case studies are often a good choice in a thesis or dissertation. They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.
You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Step 1: Select a case
Once you have developed your problem statement and research questions, you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:
Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.
Example of an outlying case study
In the 1960s the town of Roseto, Pennsylvania was discovered to have extremely low rates of heart disease compared to the US average. It became an important case study for understanding previously neglected causes of heart disease.
However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.
Example of a representative case study
In the 1920s, two sociologists used Muncie, Indiana as a case study of a typical American city that supposedly exemplified the changing culture of the US at the time.

What Is a Case Study?
Case Study:
A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject’s life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in various fields, including psychology, medicine, education, anthropology, political science, and social work.
The purpose of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.
While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, it is important to follow the rules of APA format.
Benefits and Limitations
A case study can have both strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.
One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult to impossible to replicate in a lab. Some other benefits of a case study:
On the negative side, a case study:
Researchers may choose to perform a case study if they are interested in exploring a unique or recently discovered phenomenon. The insights gained from such research can help the researchers develop additional ideas and study questions that might be explored in future studies.
However, it is important to remember that the insights gained from case studies cannot be used to determine cause and effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.
Case Study Examples
There have been a number of notable case studies in the history of psychology. Much of Freud’s work and theories were developed through the use of individual case studies. Some great examples of case studies in psychology include:
Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie’s case, her horrific abuse had denied her the opportunity to learn language at critical points in her development.
This is clearly not something that researchers could ethically replicate, but conducting a case study on Genie allowed researchers the chance to study phenomena that are otherwise impossible to reproduce.
Types of Case Studies
There are a few different types of case studies that psychologists and other researchers might utilize:
The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.
The type of case study that psychology researchers utilize depends on the unique characteristics of the situation as well as the case itself.
How to Write a Case Study
There are also different methods that can be used to conduct a case study, including prospective and retrospective case study methods.
Prospective case study methods are those in which an individual or group of people is observed in order to determine outcomes. For example, a group of individuals might be watched over an extended period of time to observe the progression of a particular disease.
Retrospective case study methods involve looking at historical information. For example, researchers might start with an outcome, such as a disease, and then work their way backward to look at information about the individual’s life to determine risk factors that may have contributed to the onset of the illness.
Where to Find Data
There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:
Section 1: A Case History
This section will have the following structure and content:
Background information: The first section of your paper will present your client’s background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.
Description of the presenting problem: In the next section of your case study, you will describe the problem or symptoms that the client presented with.
Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.
Your diagnosis: Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client’s symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.
Section 2: Treatment Plan
This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.
This section of a case study should also include information about the treatment goals, process, and outcomes.
Discussion
When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research.
In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?
More Tips
Here are a few additional pointers to keep in mind when formatting your case study:
A Word From Verywell
Case studies can be a useful research tool, but they need to be used wisely. In many cases, they are best utilized in situations where conducting an experiment would be difficult or impossible. They are helpful for looking at unique situations and allow researchers to gather a great deal of information about a specific individual or group of people.
If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines that you are required to follow. If you are writing your case study for professional publication, be sure to check with the publisher for their specific guidelines for submitting a case study.

Developing Educational Case Studies
Case studies can be used in education as a teaching tool. Many students learn better using real-life examples, and case studies can be an effective way to learn in the classroom.
Case studies have a history of being used in business schools, law schools, medical schools, and other master programs. These cases can come in different forms, with some being basic «what would you do?» type questions, and some being very detailed and requiring data analysis.
Assignments and homework for these types of studies usually require students to answer open-ended questions about a possible solution to a problem. Usually these projects are done by a group of students, as group learning is often more effective.
What Are Case Studies?
A case is basically a story. A case recounts events or problems in a way that students can learn from their complexities and ambiguities. The students can learn from the original participants in the case, whether it is business people, doctors, or other professionals.
The students are able to take over a case, and dissect key information in order to find solutions to the problems. This allows students to be able to:
1. Determine pertinent information
2. Identify the problem and its parameters
3. Identify possible solutions
4. Form strategies and ideas for action
5. Make decisions to fix the problems
The History of the Case Study Method
The founder of the case study method was Christopher Langdell, who attended Harvard Law School from 1851-1854. He was very studious, and spent most of his time in the library. This is when he started to formulate the case method.
At the time, law schools used the Dwight Method of teaching, which was a combination of lecture, recitations and drills. This method focused highly on memorization, and didn’t allow for much actual learning, just rote repetitions.
Langdell’s method was completely different. He required his students to only read cases, and to draw their own conclusions. To help them, he published sets of cases with a short introduction.
Narrative Case Studies
Narrative case studies use a comprehensive history of a problem, along with the several parts of the typical case study, to teach using the case method. With this method students try to find better solutions to problems, and find ways to analyze why their chosen solution is best.
An example of a narrative case study is the Tylenol cyanide scandal. In 1982 seven people died after ingesting Tylenol tablets laced with cyanide.
Almost immediately Tylenol’s market share dropped from 37% to 7%. Johnson & Johnson, the parent company had to work quickly to save the product. They reintroduced the product with tamper resistant packaging and a large media campaign.
Johnson & Johnson was successful. The Tylenol brand recovered and regained customer trust.
The Tylenol Scandal case study details everything that happened from beginning to end. It also details each step J&J took when turning the scandal around…both positive and negative steps.
This case study is now used in business, marketing, crisis management and other disciplines to help them solve their own problems. They can look at what J&J did to solve their problems, and use that information to fix their own issues.
As a teaching tool, this case study allows the students to analyze each step Johnson & Johnson went through, and whether or not any other solutions were possible.
Decision-Forming Case
A decision-forcing case doesn’t provide an outcome, and therefore forces the students to determine an outcome on their own. Often these cases have an epilogue, which completes the story.
The formats of these cases can vary. They can be standard written cases, PowerPoint presentations, movies or movie clips, or even TV or news stories. Regardless of the type of case, they all:
llustrate the issues typical to the type of case study
Show theoretical frameworks
Leave out assumptions
Show realistic ambiguities and tensions.
Common Case Elements
Most cases, whether legal, business, or other, have the same common elements. These are:
1. A decision maker who has a problem that needs to be solved.
2. A description of the context of the problem.
3. Data that supports the study, which could include interviews, documents or images.
Case studies can be done individually, but are usually done in a small group so students can problem solve together as a team.
The Case Study Method
The case study method is two-parted. One part is the case itself, and other part is the discussion of the case. Case studies are chosen for teaching based on how rich the narrative is, and whether the people in the study are required to make a decision or solve a problem.
When using case studies, the focus is not on the data or the analysis. The students analyze the case and try to find ways to find solutions and solve problems. This method is most often used in groups, with a focus on classroom discussion.
When students are given a study by a teacher, they should attack each case with the following checklist.
1. Thoroughly read the case and formulate your own opinions before sharing ideas with others in your group or class. You must be able to identify the problems on your own, as well as be able to offer solutions and alternatives. Before the study is discussed with the group, you must be able to form your own outline and course of action.
2. Once you have a clear understanding of the case, you can share your ideas with other members of your group.
3. Open discussion of the case and listen to the input of others in your group and class.
4. Reflect back on how your original ideas changed as a result of the group discussion.
Teaching the Case Method
Professors have several ways to use case studies in the classroom. The first way is as an adjunct to normal lectures. A lecture might discuss a certain facet of business, and the case study can be used to backup the information learned in the lecture.
This type of teaching doesn’t require large case studies, and can get by using excerpts and other extractions. The benefits of this method are that it only needs little preparation, and is a great way to introduce case studies into the classroom.
The second way is to use the case studies to challenge the student’s solutions, and help them formulate new strategies. This is the typical case study method. Students work together to formulate solutions and conclusions, and allow students to learn from each other.
Gaining Skills With The Case Method
The case method is an excellent way for students to learn new cognitive skills, as well as improve their analysis and evaluation skills. Here is a list of the skills that can be improved, and how the case method helps this process.
Knowledge – This is the student’s ability to remember information and ability to recall it.
Comprehension – This is the student’s ability to understand what they are learning. The case method helps this by using examples in a real-world context.
Application – This is the student’s ability to use their knowledge in new ways. This could mean new rules, ideas or theories. The case method helps students understand how these ideas and theories are used in the real world.
Analysis – This is the student’s ability to break down information so it can be better understood. Since analysis is the basis of the case method, this skill is greatly improved.
Synthesis – This is the student’s ability to form new ideas. Case studies help this skill by requiring them to identify new information and concepts. This is developed during group activities and discussions.
Evaluation – This is the student’s ability to judge information for a particular reason. Again, this skill is a hallmark of the case study method, and the use of cases will help improve the student’s evaluation skills.
Case Method Advantages
The largest advantage of the case study method is that students must actively and openly discuss the principals of the study. This helps develop their skills in:
Analysis, both quantitative and qualitative
Dealing with ambiguities
Case Method Criticisms
While the case study method has been seen as a very successful way of learning, it does have its criticisms. Here is a list of some of the drawbacks of the learning method.
1. Students often fight for airtime, and may not fully think through their thoughts. Many students want to be first, and place more importance in that than being right. This results in analysis that is superficial and not well thought-out.
2. Students in business management courses don’t always have the same background experience, and this can contribute to issues with experience.
3. The background information provided for the case analysis is often limited to whatever was supplied with the case.
4. If cases are too old, they may no longer be relevant. Cases that are older than 10 years shouldn’t be used if possible. This is particularly the case with business studies, since changes occur quite frequently in the business world. For example, case studies that detail companies before the Internet are often out of date. You wouldn’t want to study Barnes & Noble without knowing how eBooks affected their bottom line.
5. The case study method is not a good way to learn the technicals of finance and accounting. Not every MBA student has a strong background in accounting or finance, and vice versa. Furthermore, students don’t always attend business school at the same time in their careers. Many students get their MBA’s while in their 20’s, while other students wait until they are in their 30’s or 40’s.
6. With the case method, there isn’t a right or wrong answer. This can cause students to leave the lesson without key takeaways. In addition, this method cannot work for areas that have unique answers…this is why the case method would never work in physics or mathematics.
Those who disagree with the total case method teaching method believe the best alternative is a balance between cases and lectures.
The most recent iteration is a combination of both. They offer lectures to learn the fundamentals, and cases to determine whether or not the students understand the fundamentals enough to apply them to real-world situation.
The Case Study Method in Business School
Most top business schools use the case study method, including Harvard Business School. When students are given a case, they are required to be the decision maker, and they must read the study and identify the problems.
Once the problem has been identified, the student must analyze the situation and find solutions that can solve the problem. There can often be several possible solutions.
Students work in teams to solve the cases, discussing each facet of the case with their classmates. The teacher or instructor guides the students when necessary, and will often suggest courses of action when necessary.
Case Studies in Psychology and Social
Sciences
Case studies are used in just about every discipline, from business, to the arts, and education. But case studies are most prevalent in psychology and the social sciences, where case studies form a strong basis for all other clinical and non-clinical research.
If you are studying psychology, a part of your education will include the use of case studies. Case studies are how we learn and expand our knowledge, and how we build on older ideas and theories and attempt to make them better.
The Most Well-Known Psychological Case Studies
One of the best ways to learn about and better understand psychological case studies is to read and familiarize yourself with the most well-known case studies. These are the studies that every psychology student will learn about.
John-John
The John-John case was a pioneering study about gender and sexuality. This is one of those unique cases that cannot be recreated.
John-John focused on a set of twin boys, both of whom were circumcised at the age of 6 months. One of the twin’s circumcisions failed, causing irreparable damage to the penis. His parents were concerned about the sexual health of their son, so they contacted Dr. John Money for a solution.
Think!
What makes the John/John case study so valuable?
What can be learned about the psychological case study method itself?
Dr. Money believed that sexuality came from nurture, not nature, and that the injured baby, Bruce, could be raised as a girl. His penis was removed and he was sexually reassigned to become a girl. Bruce’s name was changed to Brenda, and his parents decided to raise him as a girl.
In this case, Dr. Money was dishonest. He believed that gender could be changed, which has since been proven false. Brenda’s parents were also dishonest, stating that the surgery was a success, when in fact that wasn’t the case.
As Brenda grew up, she always acted masculine and was teased for it at school. She did not socialize as a girl, and did not identify as a female. When Brenda was 13 she learned the truth, and was incredibly relieved. She changed her name to David, and lived the rest of her life as a male.
Jill Price
Jill Price was believed to have a condition called hyperthymesia, which gave her a remarkable memory. She could remember the tiniest details, such as what she ate for lunch 10 years prior on a random Monday.
This condition caused her great harm because she focused on all the negative events in her life, even the small ones like derogatory remarks. Price participated in the study hoping it would help her deal with her condition.
Through the study, it was determined that Price wasn’t a memory whiz, and that her abilities were completely blown out of proportion. She wasn’t able to memorize lists of words or names. Her memory was focused only on events that were relevant to her. For example, she could remember famous dates, but only if they were relevant to her or her life.
Doctors also did brain scans, and through the study, determined that she had a form of obsessive-compulsive disorder, or OCD. Price was obsessed with the negative things that had happened to her in her life, and that obsession cause the increased memory in her instance.
Future research will have to be done to corroborate this theory.
H.M.
H.M., the initials of Henry Molaison, is probably the most important case study in the field of neuroscience. HM was in a bike accident at the age of 9, and it caused brain damage that resulted in seizures.
In an attempt to end his seizures, surgeons removed small slivers of his brain from the hippocampus, which we now know is the area of the brain that is critical to memory. As a result of the surgery, HM was left with amnesia. He was unable to form new memories, and had issues remembering old memories.
This case study was the basis for future studies of human memory. Because of this study, we know that memory has two parts that work together. One part is located in the hippocampus, which is where facts and memories are stored. This one study revolutionized the study of the brain and memory.
Phineas Gage
Phineas Gage was a railroad worker who was injured in a workplace accident. He was packing gunpowder into a rock, and a spark caused the tampering iron to shoot through his cheek into his skull. His frontal lobe was damaged, but he survived the accident and was able to talk and walk immediately after.
The study was done about his personality, which immediately changed. He became short tempered and angry. He lost his friends, family, and his job. This study allowed researchers to study the frontal lobe and how it is involved in higher mental functions. It also proved that the brain was the basis for personality and behavior.
Genie
By now you are probably familiar with Genie case, and why it was such a breakthrough case study. Of all the case studies that exist, it is Genie that has allowed the most inroads to be made in the psychological field.
Genie was a feral child. She was raised in completed isolation, with little human contact. Because of the abuse she withstood, she was unable to develop cognitively. From infancy she was strapped to a potty chair, and therefore never acquired the physicality needed for walking, running and jumping.
If Genie made a noise, her father beat her. Therefore, she learned to not make a noise. Once she was found, researchers studied her language skills, and attempted to find ways to get her to communicate. They were successful. While she never gained the ability to speak, she did develop other ways to communicate. However, the public soon lost interest in her case, and with that, the funds to conduct the study.
However, her case was extremely important to child development psychology and linguistic theory. Because of her, we know that mental stimulation is needed for proper development. We also now know that there is a «critical period» for the learning of language.
The Most Well-Known Case Studies in Sociology
Sociology is a science much like psychology. In sociology, the study is of social behavior, how it originated, and how it exists today. Like most sciences, it isn’t perfect, and therefore benefits from the use of case studies.
Sociological case studies have helped us identify problems in our culture, and have helped define possible solutions. Here are some of the most well-known studies in sociology, the ones that defined and shaped the field.
Fast Food Nation
Fast Food Nation is a book by Eric Schlosser, about how the fast food industry is related to the American life.
Americans love their fast food. It is said that most toddlers are able to identify the golden arches of McDonald’s before they are able to read. Fast Food Nation uncovered some disturbing facts about the fast food industry. He discovered that fast food has widened the gap between rich and poor, and has contributed to the obesity epidemic.
His study details how much of this happened, and most of it is very unsettling.
The study also touched on other sociological issues, such as farming and ethics. Since fast food restaurants needed more beef than ever, cattle farmers would find ways to make bigger cows, and would find ways to own more cattle. This often led to overcrowding and poor care of the animals.
Milgram Obedience Studies
Stanley Milgram did a study from 1960 to 1974 in which he studied the effects of social pressure. The study was set up as an independent laboratory. A random person would walk in, and agree to be a part of the study. He was told to act as a teacher, and ask questions to another volunteer, who was the learner.
The teacher would ask the learner questions, and whenever he answered incorrectly, the teacher was instructed to give the learner an electric shock. Each time the learner was wrong, the shock would be increased by 15 volts. What the teacher didn’t know was that the learner was a part of the experiment, and that no shocks were being given. However, the learner did act as if they were being shocked.
If the teacher tried to quit, they were strongly pushed to continue. The goal of the experiment was to see whether or not any of the teachers would go up to the highest voltage. As it turned out, 65% of the teachers did.
This study opened eyes when it comes to social pressure. If someone tells you it is okay to hurt someone, at what point will the person back off and say «this is not ok!» And in this study, the results were the same, regardless of income, race, gender or ethnicity.
Think!
Why are sociological case studies necessary?
Name a sociological case study that has changed the way we think about culture today.
Nickel and Dimed
Nickel and Dimed is a book and study done by Barbara Ehrenreich. She wanted to study poverty in America, and did so by living and working as a person living on minimum wage.
She set up her experiment with three rules.
1. When looking for a job, she is unable to use her education or skills.
2. She had to take the highest paying job she gets, and do her best to keep it.
3. She had to take the cheapest housing she could find.
She lived in three cities in Florida, Maine and Minnesota.
Through her experiment, she discovered that poverty was almost inescapable. As soon as she saved a little money, she was hit with a crisis. She might get sick, or her car might break down, all occurrences that can be destructive when a person doesn’t have a safety net to fall back on.
It didn’t matter where she lived or what she did. Working a minimum wage job gave her no chances for advancement or improvement whatsoever. And she did the experiment as a woman with no children to support.
This study opened a lot of eyes to the problem of the working poor in America. By living and working as the experiment, Ehrenreich was able to show first-hand data regarding the issues surrounding poverty. The book didn’t end with any solutions, just suggestions for the reader and points for them to think about.
The Culture of Fear
This study was written in 1999 by Barry Glassner, a professor of sociology at the University of Southern California. The study investigated why Americans are so engrossed with fear.
The study examined the organizations that caused the fear, and how they profited from the anxiety that resulted. Politicians, television news and magazine programs, were all found guilty of peddling fear, which causes people to worry needlessly and cost billions of dollars.
The study investigated why Americans have so many fears today, and why Americans are more fearful now than they were 20 years ago. Life is not more dangerous now than it was 20 years ago, and yet Americans are more afraid.
Glassner discovered that there are businesses and organizations that actually profit from these fears, and as such, find ways to create them. This of course leads to wasted money, time and resources.
Much of the blame is placed with the news media, who constantly inundates us with news stories that will increase their ratings. This is called the media-effects theory.
Case Study Research – Everything You Wanted to Know
Case study research remains a controversial data collection approach. However, it is recognized widely in different social studies. That’s because it enables researchers to provide in-depth explanations of different social behaviors.
Perhaps, you’re wondering, what is a case study research? Maybe you want to know what it involves. Well, this is a research method that utilizes reports from past studies. It allows researchers to explore and understand complex issues using those reports. This research method may be considered robust, especially when researchers require holistic, in-depth investigation.
Most social sciences recognize case study research design and methods and their roles have become more prominent. This approach is used to research and write about topics in education, sociology, and community-based issues like drug addiction, poverty, and unemployment.
What is Case Study Research?
In social studies, the case study is a research method in which a phenomenon is investigated in its real-life context. It’s an empirical inquiry and research strategy that is based on an in-depth investigation of a group, event, or individual to explore the underlying principles causes.
Essentially, this study can be defined as an exploratory and descriptive analysis of a case. But, what is a case study in research? Well, a case can be anything that a researcher wants to investigate. This can include a person, a group, an event, a decision, a policy, period, institution, or any other system that can be studied historically.
Methods Used in Case Study Research
This type of research uses the same study methodology with other research types. But, the most common case study research method starts with the definition of a single case. It can also be a group comprising similar cases. These can be incorporated for a multiple-case study.
This is followed by a search to determine what is already known about the case or cases. This search can involve a review of grey literature, reports, and media content. This review plays a critical role in enabling the researchers to understand the case. It also informs researchers when it comes to developing case study research questions.
In most case studies, data is often qualitative, though not exclusively. Thus, researchers engage in case study qualitative research. When researchers use multiple cases, they analyze each case separately. Themes can arise from assertions or analysis about the entire case.
Case study research methodology can include:
Case studies are more in-depth when compared to observational research. That’s because they use several records or measures while focusing on a single subject. In some cases, a multiple-case design can be used. What’s more, a case study can be retrospective or prospective. A retrospective case study uses criteria to choose cases from historical records. Prospective case studies, on the other hand, uses established criteria while including extra cases as long as they meet the set criteria.
Because case studies use qualitative data like the one collected from interviews, they tend to be more liable. However, quantitative data and questionnaires can also be used. For instance, a case study can be used in clinical research to monitor and determine the effectiveness of treatment.
Types of Case Study Research
When you research case study, you explore causation to identify the underlying principles. But, they can’t be generalized to a larger population the way researchers do when conducting experimental research. They also can’t provide predictive power the same way correlational research can do. Rather, they provide extensive data that can be used to develop new hypotheses that can be used for further research. It can also be used to study rare conditions or events that are hard-to-study.
A case study research paper can fall into any of these categories:
People may define case study research differently based on these major types of this investigation. Nevertheless, it’s an intensive and systematic investigation of a group, community, individuals, or other units where the researchers examine in-depth data that relate to several variables.
Example of Case Study Research
Case study definition in research may vary. However, students should be keen to choose topics they are comfortable researching and writing about. Here are case study research question examples that be used for this kind of investigation.
Different data collection methods can be used to assess and understand each case separately. This can lead to a better understanding of the phenomenon under investigation. The goal of the case study research design is to provide a framework that can be used to evaluate and analyze complex issues. For instance, in the last two examples above, a case study can be used to shed light on the nursing practice as a holistic approach. It can also provide a perspective that will inform the nurses to give improved care to their patients.
How to Do Case Study Research
When writing a case study paper, follow these steps, suggested by our writing professionals:
In a nutshell, a case study entails collecting data that leads to a better understanding of a phenomenon. The methodology of a case study provides a framework that is used to analyze and evaluate more complex issues.

What is a case study?
Case studies are research methodologies. They examine subjects, projects, or organizations to tell a story.
Numerous sectors use case analyses. The social sciences, social work, and psychology create studies regularly.
Healthcare industries write reports on patients and diagnoses. Marketing case study examples, like the one below, highlight the benefits of a business product.
Now that you know what a case study is, we explain how case reports are used in three different industries.
What is a business case study?
A business or marketing case study aims at showcasing a successful partnership. This can be between a brand and a client. Or the case study can examine a brand’s project.
There is a perception that case studies are used to advertise a brand. But effective reports, like the one below, can show clients how a brand can support them.
Hubspot created a case study on a customer that successfully scaled its business. The report outlines the various Hubspot tools used to achieve these results.
Hubspot also added a video with testimonials from the client company’s employees.
So, what is the purpose of a case study for businesses? There is a lot of competition in the corporate world. Companies are run by people. They can be on the fence about which brand to work with.
Business reports stand out aesthetically, as well. They use brand colors and brand fonts. Usually, a combination of the client’s and the brand’s.

What is a case study in psychology?
In the field of psychology, case studies focus on a particular subject. Psychology case histories also examine human behaviors.
Case reports search for commonalities between humans. They are also used to prescribe further research. Or these studies can elaborate on a solution for a behavioral ailment.
The American Psychology Association has a number of case studies on real-life clients. Note how the reports are more text-heavy than a business case study.
Famous psychologists such as Sigmund Freud and Anna O popularised the use of case studies in the field. They did so by regularly interviewing subjects. Their detailed observations build the field of psychology.
It is important to note that psychological studies must be conducted by professionals. Psychologists, psychiatrists and therapists should be the researchers in these cases.
What is a case study in research?
Research is a necessary part of every case study. But specific research fields are required to create studies. These fields include user research, healthcare, education, or social work.
For example, this UX Design report examined the public perception of a client. The brand researched and implemented new visuals to improve it. The study breaks down this research through lessons learned.
Clinical reports are a necessity in the medical field. These documents are used to share knowledge with other professionals. They also help examine new or unusual diseases or symptoms.
The pandemic has led to a significant increase in research. For example, Spectrum Health studied the value of health systems in the pandemic. They created the study by examining community outreach.
The pandemic has significantly impacted the field of education. This has led to numerous examinations on remote studying. There have also been studies on how students react to decreased peer communication.
Social work case reports often have a community focus. They can also examine public health responses. In certain regions, social workers study disaster responses.
You now know what case studies in various fields are. In the next step of our guide, we explain the case study method.
What is the case study method?
A case analysis is a deep dive into a subject. To facilitate this case studies are built on interviews and observations. The below example would have been created after numerous interviews.
Case studies are largely qualitative. They analyze and describe phenomena. While some data is included, a case analysis is not quantitative.
There are a few steps in the case method. You have to start by identifying the subject of your study. Then determine what kind of research is required.
In natural sciences, case studies can take years to complete. Business reports, like this one, don’t take that long. A few weeks of interviews should be enough.
The case method will vary depending on the industry. Reports will also look different once produced.
As you will have seen, business reports are more colorful. The design is also more accessible. Healthcare and psychology reports are more text-heavy.
Benefits of case studies
Designing case reports takes time and energy. So, is it worth taking the time to write them? Here are the benefits of creating case studies.
For example, the business study below creates a story around a brand partnership. It makes for engaging reading. The study also shows evidence backing up the information.
We’ve shared the benefits of why studies are needed. We will also look at the limitations of creating them.
Limitations of case studies
There are a few disadvantages to conducting a case analysis. The limitations will vary according to the industry.
These are some of the common weaknesses of creating case reports. If you’re on the fence, look at the competition in your industry.
Other brands or professionals are building reports, like this example. In that case, you may want to do the same.
Types of case studies
There are six common types of case reports. Depending on your industry, you might use one of these types.
We go into more detail about each type of study in the guide below.
Descriptive case studies
When you have an existing hypothesis, you can design a descriptive study. This type of report starts with a description. The aim is to find connections between the subject being studied and a theory.
Once these connections are found, the study can conclude. The results of this type of study will usually suggest how to develop a theory further.
A study like the one below has concrete results. A descriptive report would use the quantitative data as a suggestion for researching the subject deeply.
Explanatory case studies
When an incident occurs in a field, an explanation is required. An explanatory report investigates the cause of the event. It will include explanations for that cause.
The study will also share details about the impact of the event. In most cases, this report will use evidence to predict future occurrences. The results of explanatory reports are definitive.
Note that there is no room for interpretation here. The results are absolute.
The study below is a good example. It explains how one brand used the services of another. It concludes by showing definitive proof that the collaboration was successful.
Another example of this study would be in the automotive industry. If a vehicle fails a test, an explanatory study will examine why. The results could show that the failure was because of a particular part.
Exploratory case reports
An explanatory report is a self-contained document. An exploratory one is only the beginning of an investigation.
Exploratory cases act as the starting point of studies. This is usually conducted as a precursor to large-scale investigations. The research is used to suggest why further investigations are needed.
An exploratory study can also be used to suggest methods for further examination.
For example, the below analysis could have found inconclusive results. In that situation, it would be the basis for an in-depth study.
Intrinsic case studies
Intrinsic studies are more common in the field of psychology. These reports can also be conducted in healthcare or social work.
These types of studies focus on a unique subject, such as a patient. They can sometimes study groups close to the researcher.
The aim of such studies is to understand the subject better. This requires learning their history. The researcher will also examine how they interact with their environment.
For instance, if the case study below was about a unique brand, it could be an intrinsic study.
Once the study is complete, the researcher will have developed a better understanding of a phenomenon. This phenomenon will likely not have been studied or theorized about before.
Examples of intrinsic case analysis can be found across psychology. For example, Jean Piaget’s theories on cognitive development. He established the theory from intrinsic studies into his own children.
Instrumental case studies
This is another type of study seen in medical and psychology fields. Instrumental reports are created to examine more than just the primary subject.
When research is conducted for an instrumental study, it is to provide the basis for a larger phenomenon. The subject matter is usually the best example of the phenomenon. This is why it is being studied.
Take the example of the fictional brand below.
Assume it’s examining lead generation strategies. It may want to show that visual marketing is the definitive lead generation tool. The brand can conduct an instrumental case study to examine this phenomenon.
Collective case reports
Collective studies are based on instrumental case reports. These types of studies examine multiple reports.
There are a number of reasons why collective reports are created:
A researcher could use multiple reports, like the one below, to build a collective case report.
FAQs about case studies
What makes a case study a case study?
A case study has a very particular research methodology. They are an in-depth study of a person or a group of individuals. They can also study a community or an organization. Case reports examine real-world phenomena within a set context.
How long should a case study be?
The length of studies depends on the industry. It also depends on the story you’re telling. Most case studies should be at least 500-1500 words long. But you can increase the length if you have more details to share.
What should you ask in a case study?
The one thing you shouldn’t ask is ‘yes’ or ‘no’ questions. Case studies are qualitative. These questions won’t give you the information you need.
Ask your client about the problems they faced. Ask them about solutions they found. Or what they think is the ideal solution. Leave room to ask them follow-up questions. This will help build out the study.
