Review Questions

• How do different data collection methods impact the validity of research findings?
  • Different data collection methods can greatly influence the validity of research findings. For instance, qualitative methods like interviews allow for deeper insights into participants' experiences, while quantitative methods like surveys can provide statistical reliability. Choosing the right method ensures that researchers gather relevant and accurate data that addresses their specific research questions, ultimately affecting how well conclusions can be drawn.
• Discuss the advantages and disadvantages of using qualitative versus quantitative data collection methods.
  • Qualitative data collection methods offer rich, detailed insights into participant experiences but may lack generalizability due to smaller sample sizes. In contrast, quantitative methods can analyze larger populations statistically but might overlook individual nuances. The choice between these methods depends on the research objectives; a mixed-methods approach often provides a balanced understanding by leveraging the strengths of both types.
• Evaluate how ethical considerations should influence the selection of data collection methods in research.
  • Ethical considerations are critical when selecting data collection methods because they ensure the protection of participants' rights and welfare. Researchers must choose methods that enable them to obtain informed consent and maintain confidentiality throughout the process. Additionally, ethical approaches help to build trust with participants, which can enhance the quality of data collected and contribute to more credible research outcomes.
