Field Interviews Discussion

What is the significance of field data gathering through individual respondent interviews?
What is the process for developing research protocols?
How are the respondents chosen?
How do you test the validity of the research protocols?

Write a 300-word post detailing how your case study will employ the gathering of important data from the field respondents through interviews. The process should address the Empirical Unknowns, research protocols/questions (Creswell & Creswell 2018, 133-135), interview process, how the data is captured (recording interviews, written format, etc.), and electronic data software used to assist in managing the data collection process through the field interviews and other data collection techniques. Be sure to include information from the text and cite them appropriately.
