Case studies involve analyzing a small sample size or a single case in detail, which may not necessarily reflect the whole population or provide an accurate representation of the national rate of unemployment. Therefore, overestimating the national rate of unemployment based on just three case studies may be misleading. Surveys and random samples are typically used to gather data from a larger population and are generally more reliable in providing accurate information about a specific phenomenon. Dependent variables are not directly related to the issue of overestimating the national rate of unemployment.
