The Correct Answer and Explanation is :
The correct answers for solutions to nonresponse are:
- A. reduce interview error
- B. attempt callbacks
- G. offer rewards and incentives
- H. use stratified sampling
Explanation:
Nonresponse refers to situations where individuals selected to participate in a survey or study do not respond. This can lead to biased results if the nonrespondents differ significantly from those who participate. Below are solutions to address nonresponse:
- A. Reduce interview error: By improving the quality of interviews, ensuring clear and unbiased questions, and training interviewers effectively, we reduce the risk of errors that may discourage respondents from participating. The clearer and more professional the process, the more likely participants will engage.
- B. Attempt callbacks: One of the most direct strategies to address nonresponse is to attempt callbacks to people who initially did not respond. This increases the likelihood of reaching a full sample, as some respondents might be unavailable or need reminders to participate.
- G. Offer rewards and incentives: Offering incentives or rewards (like gift cards, discounts, or other perks) can encourage people to participate in surveys. Incentives increase motivation for participation, particularly in cases where there might be reluctance or a perceived lack of immediate benefits for respondents.
- H. Use stratified sampling: Stratified sampling is a technique where the population is divided into distinct subgroups (strata), and individuals are randomly selected from each stratum. This method ensures that different segments of the population are adequately represented, which can help reduce bias from nonresponse if certain groups are underrepresented in the initial response.
Why Other Options Are Not Solutions to Nonresponse:
- C. Reduce undercoverage: While reducing undercoverage is important for ensuring the representativeness of a sample, it doesn’t directly address nonresponse. Undercoverage relates to failing to capture certain groups in the sampling process, while nonresponse focuses on the people who were selected but did not respond.
- D. Change wording of questions: Changing the wording of questions can improve clarity and response rates, but it is not directly related to addressing nonresponse itself. It may help with comprehension or participation, but the primary issue of getting responses is not solved by wording alone.
- F. Use convenience sampling: Convenience sampling involves selecting participants based on ease of access, which can lead to biased results and does not directly address the issue of nonresponse. It may not reflect the full population and could worsen the problem by excluding important segments.
