Nonresponse is a growing problem for marketing researchers. The problem is more prevalent in mail surveys, in which respondents are asked to fi ll out a questionnaire and return it by mail. The reasons for nonresponse could be that the respondents are unavailable, are not willing to participate, or are unable to answer the survey questions. However, many organizations may still consider using this survey mode because it is self-administered and inexpensive. Suggest ways to increase the response rate.
