This research examined the issue of nonresponse bias and how it was reported in nonexperimental quantitative research published in the "Delta Pi Epsilon Journal" between 1995 and 2004. Through content analysis, 85 articles consisting of 91 separate samples were examined. In 72.5% of the cases, possible nonresponse bias was not examined in the respective study. Of those who reported addressing the issue, comparing respondents to nonrespondents was the technique most frequently employed to understand possible systematic differences between the groups. Chi-square analyses did not reveal statistically significant differences between sampling technique (probability and nonprobability), response rate, and nonresponse bias checking. Response rates for the studies ranged from 12%-100%, with a mean of 62.2%. The implication for the external validity of business education research is discussed and future research is recommended.
