Which method is NOT typically used for descriptive studies?

Descriptive studies are focused on providing a comprehensive view of a phenomenon, often through methods that allow for detailed observation and reporting of behaviors and characteristics. The primary goal is to gather detailed information without manipulating variables, which is essential for achieving a deeper understanding of the subject being studied.

Case studies involve an in-depth examination of a single individual or a small group, making it ideal for collecting qualitative data. Surveys allow researchers to gather data from a larger population through questionnaires or interviews, providing insights into trends and patterns. Observational studies involve directly watching subjects in their natural environment to record their behavior without interference.

In contrast, experiments are designed to test hypotheses by manipulating one or more independent variables while observing the effect on dependent variables. This manipulation is fundamental to experimental design and aims to establish cause-and-effect relationships rather than simply describing phenomena. Because experiments involve intervention and control over variables, they do not fit within the realm of descriptive studies, which focus solely on observation and description. Therefore, experiments are not typically used for descriptive studies.
