In qualitative research, which of the following best exemplifies the ethical considerations necessary when conducting case studies and using data triangulation?

In qualitative research, ethical considerations are very important, especially when doing case studies and using data triangulation. Ethical considerations mean that researchers must respect the rights and privacy of the people they study. For example, if a researcher interviews someone about their personal experiences, they must get permission to share that information and ensure it is kept confidential. Data triangulation, which involves using multiple sources of information to get a richer understanding, also requires careful attention to ethics. The researcher must make sure that all sources of data are treated fairly and that participants know how their information will be used, ensuring transparency and trust.
