Final answer:
Case studies provide a deep amount of information, but have limited generalizability.
Step-by-step explanation:
The major advantage associated with case studies is the depth of information they provide.
Case studies collect a rich amount of information on specific cases or individuals, allowing researchers to gain deep insight into the phenomenon being studied. However, a weakness of case studies is their limited generalizability, as they focus on unique cases that may not represent the larger population. Despite this limitation, case studies offer valuable insights and can be used to generate hypotheses for further research.
