A case study is for an observer or the affected person. A case study is a research approach as well as a tool. It’ an in-depth analysis of a phenomenon that provides personal rather than objective information. It gives precise information about the phenomena but cannot generalize beyond that.

Case studies designed to investigate unique topics within the limits of a particular location, circumstance, or organization. The case study research method can classified into three types based on its design: explanatory, descriptive, and exploratory.

  • Explanatory case studies try to address ‘how’ or ‘why’ questions with minimal influence over the occurrence of events on the researcher’s part.
  • The goal of descriptive case studies is to examine the pattern of interpersonal interactions after some time has passed.
  • The goal of exploratory case studies is to discover answers to the questions “what” and “who.” Additional data collecting methods, such as interviews, surveys, and experiments, frequently used by most professional dissertation writing service UK with the exploratory case study data collection method.


There are six different sorts of case studies:

  1. Community Studies: A community study is a corporative description. You can take the dissertation help from analyzing a group of individuals living together in a specific geographical region. The community study looks at things like the community’s location, current economic activity, historical development, appearance, climate and natural resources, how people live, the social structure, goals and life values, and an assessment of the community’s social institutions that meet human needs, among other things.
  2. Casual Comparative Studies: Another study looks for solutions to problems by looking at informal partnerships. What factors appear linked to specific events, conditions, or types of behavior? The relative importance of these characteristics can be studied using descriptive research methods.
  3. Activity Analysis: In both industry and various sorts of social organizations, analyzing the activities or processes that an individual is called upon to complete is critical. This kind of analysis can used in any field and at any level of responsibility. The superintendent, administrator, teacher, and caretaker jobs in the social system have thoroughly examined to determine what these personnel perform and require.
  4. A Follow-up Study: A follow-up study looks at people who have left an institution. After completing a program, a therapy, or a course of study to see how the institution and its agenda have affected them. Examining their position or soliciting their thoughts can provide insight into the institute’s program’s adequacy or inadequacy. These studies allow an institution to assess various components of its curriculum in light of actual outcomes.
  5. Trend Studies: Trend studies, also known as prediction studies, are a fascinating use of the descriptive approach. Based on a longitudinal analysis of collected data, demonstrating what has happened in the past, what the current situation reveals, and what the future holds.


The following are the key benefits of case studies:

  1. Forming a sound hypothesis: A case study aids in formulating sound hypotheses. After thoroughly studying and analyzing the numerous situations, the researcher can derive several generalizations that can developed into valuable theories. All agree that the only reliable hypothesis sources are the review of relevant literature and case studies.
  2. Helpful in creating questionnaires and timetables: Case studies are helpful in creating questionnaires, schedules, and other forms. When a questionnaire is completed following a thorough case study, the characteristics of the group and individual units are revealed and the type of response that is likely to be accessible and the people’s likes and dislikes. This makes it easier to get a fast response.
  3. Sampling: A case study can assist with sample stratification. By examining individual units, the researcher can categorize them into distinct classes or kinds, making complete stratification of the sample easier.
  4. Locating deviant cases: The case study allows for identifying strange circumstances. There is a general inclination to overlook them, but they are critical for scientific analysis. The consideration of such situations aids in the clarification of the theory itself.
  5. Process study: In cases when the problem under study is a process rather than a single incident, such as courting, clique formation, and so on, the case study is the suitable method because case data is required for practical analysis of such problems.


  1. Subjective bias: Subjectivity in data collection for supporting or rejecting a specific explanation and a personal perspective on the investigation influences the study’s findings and conclusions.
  2. Objectivity issue: The researcher may create self-justificatory data that are far from factual due to excessive affiliation with the social unit under inquiry.
  3. Comparison difficulty: Due to wide variability among human beings in terms of response and behavior, attitudes and values, social setting and circumstances, and so on, the researcher finds it difficult to identify two social units that are identical in every way. This makes it challenging to compare cases properly.
  4. A time, energy, and money-consuming method: Preparing a case history takes a long time and a lot of human power; therefore, there’s a good chance that most of the cases will go astray. Only a few researchers can afford to use the case study approach because of these difficulties.
  5. Untrustworthy source material: Personal records and life history are the two primary sources of case study information. However, the documents or the social units’ personal experiences may not offer a realistic picture in both circumstances. On the other hand, the social team may attempt to conceal or color his unpleasant facts. As a result, the conclusions reached do not provide a complete picture or reliable results.


Case studies are a significant and valuable approach to gathering data, particularly in the case of rare phenomena. Without a doubt, what you gain in-depth with case studies you lose in breadth is an inevitable compromise. That must be realized from the start of the research process. As a result, neither an advantage nor a disadvantage exists because the benefits/drawbacks of one side balance out the benefits/drawbacks of the other.
