What Nonresponse is
Nonresponse occurs when a respondent does not answer one or more questions in a survey or does not answer the survey at all. This can lead to bias in the survey results if the nonresponse is not taken into account.
Steps for Nonresponse:
-
Identify the survey questions with the highest nonresponse rate.
-
Investigate the possible causes of the nonresponse.
-
Implement strategies to reduce the nonresponse rate. This could include providing more incentives, introducing new survey designs, or making the survey easier to complete.
-
Monitor the nonresponse rate to ensure that the strategies are effective.
-
Consider weighting the survey results to account for any potential bias caused by nonresponse. This involves adjusting the survey results to better represent the population of interest.
Examples
- Nonresponse in opinion polling due to lack of willingness to answer questions.
- Nonresponse in survey research due to lack of contact information for potential respondents.
- Nonresponse in medical studies due to lack of patient consent.
- Nonresponse in longitudinal studies due to attrition.
- Nonresponse in population census due to lack of awareness or unwillingness to participate.
