Re: What is the Appropriate Sample Size for a Customer Survey?
Thanks for the excellent reference/attachment. I have a very little knowledge of statistics that's why I found this a little bit harder.
Let me give you an update. We conducted customer survey using two channels, e-mail and walk-in. We are on our third week but very few responses. From your attached file I refered to the table to determine the recommended sample size. Since there are 8,000 active accounts/customers, the recommended sample size for categorical data could be 262 or 367 or 613. My question is this.. Should I stop at 262 or 367 or 613 samples even if the response is low? Or should I continue conducting surveys until we reached 262 0r 367 0r 613 responses?
