Peer reviewedKrushat, W. Mark; Molnar, John I. – Evaluation Practice, 1993
After a mailed questionnaire and two follow-ups, hard-core survey nonrespondents were contacted to ask why they had not responded and what they would have answered had they responded. Results from 28 subjects indicate that efforts to pursue nonrespondents may be unnecessary, because bias resulting from nonresponse appeared minimal. (SLD)
