research participants and promote honesty, integrity, and transparency in research practices.
24. **What ethical considerations are important in research involving human subjects?**

- Ethical considerations include informed consent, confidentiality, voluntary participation, minimizing

harm, and disclosing potential conflicts of interest.

25. **Explain the peer review process in research publication.**

- Peer review involves independent experts evaluating the quality, validity, and significance of
research manuscripts before publication in scholarly journals.

26. **How does reflexivity apply to qualitative research?**

- Reflexivity encourages researchers to critically reflect on their own biases, assumptions, and
experiences that may influence the research process and findings.

27. **Describe the concept of triangulation in research.**

- Triangulation involves using multiple methods, data sources, or researchers to validate findings and
enhance the credibility and reliability of research results.

28. **What is action research?**

- Action research is a participatory approach where researchers and practitioners collaborate to

address real-world problems and improve practices within specific organizational or community settings.

29. **Explain the concept of reliability and validity in research instruments.**

- Reliability refers to the consistency of measurement, while validity assesses whether a research
instrument accurately measures what it intends to measure.

30. **What are the steps involved in conducting a systematic review in research?**

- Steps include formulating research questions, identifying relevant studies, selecting and appraising
studies, synthesizing findings, and reporting results according to established guidelines.

31. **How can research findings be generalized to broader populations?**

- Generalizability refers to the extent to which research findings can be applied to populations beyond
the study sample, influenced by sampling methods, research design, and context.
32. **Explain the Delphi method in research.**

- The Delphi method is a structured approach involving multiple rounds of surveys or questionnaires
with experts to achieve consensus on complex issues or forecasts.

33. **Describe the difference between cross-sectional and longitudinal research designs.**

- Cross-sectional research collects data at a single point in time from different individuals or groups.
Longitudinal research collects data from the same individuals or groups over multiple time points to
examine changes over time.
