Answer:
Here are some considerations for when to use a questionnaire, interview guide, or both:
Questionnaire:
Questionnaires are best suited for collecting data from a large sample size.
They can be distributed electronically or in print, and participants can complete them at their convenience.
Questionnaires are useful when the research topic is well-defined and requires standardized data collection.
Interview Guide:
An interview guide is best suited for collecting data from a small sample size.
They provide more detailed and nuanced data, as they allow for follow-up questions and probes.
Interview guides are useful when the research topic is complex and requires in-depth exploration.
Both:
A combination of both methods can be useful when the research topic requires a mixed-methods approach.
The questionnaire can be used to collect standardized data from a large sample, and the interview guide can be used to explore specific themes in greater depth with a smaller sample.
In conclusion, the decision to use a questionnaire, interview guide, or both depends on the research question, the sample size, and the level of detail required in the data. Researchers should carefully consider these factors and choose the method or combination of methods that is best suited for their research.
