The Importance of Random Sampling When Conducting Visitor Surveys

Allan S. Mills, Seoho Um, Edward G. McWilliams, Ronald W. Hodgson

Abstract


Data from two on-site visitor surveys illustrate the importance of random sampling. A haphazard sample of Folklife Festival visitors in Texas produced results different from those of a random sample of the same visitor population. A sample of Lake Tahoe area skiers in which skier selection was left to interviewers also produced different results from a completely randomized respondent sample in which the selection of skiers was predetermined. Data from visitor surveys that do not randomly select respondents should only be used with great caution.?

Keywords
