Doing an masters by research at UCC and my main data source was an online survey via surveymonkey sent to a sample group of multi-national company managers. The survey was well received I think, but I believe company firewalls etc may have prevented the email invite and link to the survey from reaching many. Still, I'll end up with a response rate of about 30%,out of roughly 220 invites sent. Not analysed the data in detail yet. My question is : on the face of it, is a 30% response rate broadly acceptable to examiners? Asking my supervisor the same question, but interested in a wider 'take' on this.
FYI time constraints meant this was the most expedient method to gather data, but I think next time, I'd have back-ups.
