D
Describe the case study method of research, outlining the limitations of this method and discussing when this method might be the most appropriate.
The case study method of research involves in-depth, detailed examination of a specific instance or event, often within its real-life context. This method is commonly used in social sciences, psychology, and business studies to gain a deeper understanding of complex phenomena and to generate hypotheses for further research.
One of the main limitations of the case study method is its lack of generalizability. Because it focuses on a single case or a small number of cases, it can be difficult to apply the findings to a larger population or to make broad generalizations. Additionally, the researcher's subjective interpretation and bias can influence the results, leading to potential validity and reliability issues.
Despite these limitations, the case study method can be most appropriate in certain situations. For example, when studying rare or unique phenomena that cannot be easily replicated in a laboratory setting, the case study method allows researchers to explore these complex issues in their natural context. It can also be useful for generating new hypotheses and theories, as well as for providing rich, detailed descriptions of individual cases.
In conclusion, while the case study method has its limitations, it can be a valuable research tool when used appropriately. Researchers should carefully consider the specific research question and the nature of the phenomenon being studied before deciding whether the case study method is the most appropriate approach.
An experiment that does not allow for the determination of causality lacks:
A
In an experiment, a researcher manipulates the dependent variable in order to observe whether the behavior measured by the independent variable changes.

Peter believes listening to relaxing music will improve memory.He designs a study in which 15 people listen to relaxing music while studying for 30 minutes and 15 people study in a quiet room for 30 minutes.He measures how much they remember from the material they studied.In this example, the independent variable is:

The main reason it is not possible to determine causality from a correlation is:
Case studies can provide researchers with an important historical perspective that can help them form hypotheses about the possible causes of a behavior or psychological problem.
