What is non-response error?
Non-response errors result from a failure to collect complete information on all units in the selected sample. Non-response errors affect survey results in two ways. First, the decrease in sample size or in the amount of information collected in response to a particular question results in larger standard errors.
What is an example of response bias?
Response bias (also called survey bias) is the tendency of a person to answer questions on a survey untruthfully or misleadingly. For example, they may feel pressure to give answers that are socially acceptable.
What are the sources of non sampling error?

- Eye on the Prize: Provide Incentives.
- Don’t Waste Their Time: Keep Surveys Relevant.
- Be Top-of-Mind: Offer Surveys in Multiple Channels.

Minimizing Sampling Error
- Increase the sample size. A larger sample size leads to a more precise result because the study gets closer to the actual population size.
- Divide the population into groups.
- Know your population.
- Randomize selection to eliminate bias.
- Train your team.
- Perform an external record check.
What are the two types of sampling errors?
The total error of the survey estimate results from the two types of error: sampling error, which arises when only a part of the population is used to represent the whole population; and. non-sampling error which can occur at any stage of a sample survey and can also occur with censuses.
