Detailed explanation-1: -Studies with low response rates may produce prevalence estimates that are biased by selective non-response. That is, the chance that someone will participate in the survey may be related to the parameter being measured.
Detailed explanation-2: -A major disadvantage of a mail survey is the length of the field period that is required to gain a reasonably high response rate, due to the multiple follow-up mailings this requires.
Detailed explanation-3: -On the other hand, mail survey response rates average closer to 30-40% and can climb into the 60-70% range. Particularly when a non-response bias is vital, attaining a high response rate can be of the upmost importance.
Detailed explanation-4: -Surveys with too many questions or poorly constructed answer options will likely result in your user quitting the survey part way through, and they will be less inclined to answer future surveys. When constructing your survey, focus on the BIG questions.
