A case comparison study refers to a research method used in various disciplines, including social sciences, medicine, and business, to examine and evaluate two or more distinct cases or subjects to uncover similarities, differences, patterns, and relationships between them. This method enables researchers to conduct a detailed investigation, analyze and contrast multiple cases to gain a comprehensive understanding of a particular phenomenon, event, or concept.
In a case comparison study, researchers select cases with certain characteristics or variables of interest and carefully examine each case separately, focusing on both the similarities and differences among them. This approach allows for the identification of commonalities and variations in the cases, enabling researchers to draw conclusions, identify patterns, and develop theories or hypotheses based on the findings.
The case comparison study involves collecting and analyzing various types of data, such as qualitative and quantitative data, including interviews, surveys, observations, documents, and statistical information. Researchers thoroughly analyze the collected information, compare the cases across the chosen variables, and interpret the results.
This method often employs rigorous analysis techniques, such as within-case and cross-case analysis, to explore the unique characteristics of each case and provide insights into the relationships and interactions between cases. The ultimate goal of a case comparison study is to generate new knowledge, contribute to existing theories, and inform decision-making by providing a rich understanding of the phenomena under investigation.
