I have a research study that has a questionnaire for medical residents.
However I am not allowed to directly email the link to them, but can post the link on the social media that residents have access to it:
A- How can I calculate the response ratio since it will not be clear how many residents have seen the link / or received the link as the denominator of the ratio?
B- Is it OK to just post the link in Social media? ( because anybody even a non-resident may go and fill the questionnaire).
Thank you,
AS
