Final answer:
A major advantage of case studies is the detailed information they provide, offering profound insights into individual cases which helps in understanding unique circumstances deeply.
Step-by-step explanation:
A major advantage of case studies is detailed information. Case studies provide an in-depth look at individual cases, allowing researchers to gain a profound understanding of the unique circumstances and variables involved. This can be particularly valuable when studying exceptional instances or when a deep, comprehensive understanding is required. This method can contribute a precious amount of insight into the cases it examines.
Although case studies are rich in content, they are less advantaged when it comes to generalizability. Because case studies often focus on a specific individual or group, it may be difficult to apply these findings to a larger population. The uniqueness of each case can make drawing broad conclusions challenging, which is why generalizability is often considered a limitation rather than a strength of this research method. Moreover, case studies do not typically involve large sample sizes, and collecting the in-depth data they are known for is not a process that can be described as quick data collection.
