Case Study vs Grounded Theory: What’s the Difference?
When it comes to research methods, there are many to choose from. Two popular methods are case studies and grounded theory. But what are the differences between these two approaches? In this blog post, we’ll explore the differences between case study and grounded theory and how to choose the right approach for your research project.
What is a Case Study?
A case study is an in-depth exploration of a single person, group, event, or situation. It involves gathering information from a variety of sources including interviews, documents, and observations. The researcher uses the data to gain an understanding of the situation and draw conclusions.
Case studies are particularly useful in exploring complex issues and developing new theories. They can also be used to test existing theories or to identify patterns in a particular situation.
What is Grounded Theory?
Grounded theory is an approach to research that seeks to generate new theories from data collected through systematic observation, interviewing, and analysis. The researcher begins with a few broad questions and then collects data to refine the questions and develop a theory.
Unlike a case study, grounded theory is not focused on a single person, group, or situation. Instead, it seeks to identify patterns and relationships in a variety of data. The researcher then uses the data to develop a theory about the phenomena under study.
Which Method Should You Choose?
When deciding which method to use for your research project, consider the type of information you need and the research question you are trying to answer. If you need to gain an in-depth understanding of a single person, group, or situation, then a case study may be the right approach. If you need to identify patterns or relationships between different elements, then grounded theory may be a better approach.
Conclusion
Case studies and grounded theory are both valuable research methods that can provide valuable insights into complex issues. However, the most appropriate approach for your research project depends on the type of information you need and the research question you are trying to answer.

Frequently asked questions
What is the difference between a case study and grounded theory?
A case study examines one bounded case in depth, such as a person, group, event or organization, using several data sources. Grounded theory builds a new theory from data through systematic coding and constant comparison, across many observations rather than a single case.
When should I use a case study versus grounded theory?
Use a case study to understand a specific situation in depth, especially for descriptive or explanatory questions. Use grounded theory when you want to develop a new theory about a process and no existing framework fits your data.
What is the difference between a case study and phenomenology?
A case study looks at a bounded system using multiple data sources. Phenomenology explores the essence of lived experience, usually through interviews with people who went through the same phenomenon. Case studies describe a case, while phenomenology describes shared experience.
Can you combine case study and grounded theory approaches?
Yes. Researchers sometimes use grounded theory coding methods to analyze data collected within a case study design. Some methodologists warn that the two approaches have different aims, so state clearly how you are combining them and why.
