With nearly every survey Resource Science Division conducts, administration, budgeters, and staff ask “Wouldn’t online surveys save MDC money?” and we respond, “It depends!” Online surveys have become attractive as a presumably economical way to measure constituents’ preferences, opinions, and attitudes. However, issues such as non-response bias, sample validity, and sampling error due to internet access differences in the population can have effects on representativeness, reliability, and accuracy. We examined response rates, responses, demographics, and potential sources of bias in the 2016 post-season firearms deer and deer hunter opinion surveys using 1) a mail-back paper survey and 2) an online survey sent to a sample of those with an email address in the point-of-sale (POS) system.
