Question

Which of the following sampling techniques would most likely result in a non-response bias?

- Cluster Sampling

- Systematic Sampling

- Simple Random Sampling

- Stratified Sampling

- Voluntary Sampling

Answer 1

Non-response bias can occur when subjects who refuse to take part in a study, or who drop out before the study can be completed, are systematically different from those who participate.

So, Voluntary Sampling is most likely result in a non-response bias because some important part of people may choose not to participate.
