In my research, respondents are full-time academia of four specific universities
📷 Sampling frame (lecturer/Senior lecturer, Associate prof/ Prof) = Total 7244 Academia
📷 Sampling technique (stratified random sampling) will be using to reach respondents
Therefore, my question is
- Can I use a particular university and particular faculty to conduct the pilot study or do I need to conduct the pilot study among four universities and various faculties?
Thank you very much.
