Several researchers have examined the effect of giving
subjects a deadline for responding. While a deadline will
usually reduce the time from the mailing until the
returns begin arriving, it appears that it does not
increase response, and may even reduce the response. One
possible explanation is that a cutoff date might dissuade
procrastinators from completing the questionnaire after
the deadline has past. The timeline for Internet surveys is much
different from a mail survey. While mail surveys take weeks, Internet
surveys take days. You will receive about 90% of the response within
three days after the email invitation is sent. |
