An "esettanulmány," or case study, is a research method that involves an in-depth analysis of a specific instance, event, or individual. It is commonly used in various fields such as business, psychology, and education to explore complex issues in real-life contexts. The goal is to gather detailed information that can provide insights and inform future practices. Case studies often include qualitative and quantitative data, allowing researchers to examine patterns and draw conclusions. They can be instrumental in understanding the effectiveness of strategies, interventions, or programs, making them valuable tools for academics and practitioners alike.
