Question

Quizplus · Accepted Answer

Nonsampling errors are errors that occur during the data collection process itself. The best way to reduce these errors is to improve data collection techniques. This can be done by training interviewers or survey administrators, pretesting the survey, using clear and unambiguous questions, and using reliable and valid measurement instruments. Increasing sample size may help to reduce sampling error but will not prevent nonsampling errors. Offering incentives or substituting houses for not-at-homes may improve response rates but will not necessarily reduce nonsampling errors. Nonsampling errors cannot be completely eliminated, but efforts can be made to minimize their impact.
