What is non-response bias?
Nonresponse bias occurs when survey participants are unwilling or unable to respond to a survey question or an entire survey. Reasons for nonresponse vary from person to person. To be considered a form of bias a source of error must be systematic in nature. Nonresponse bias is not an exception to this rule.
What is an example of non-response?
For example, a survey sent out on a new phone app may only reach younger people who have the app, which leads to nonresponses from older members of the population. The survey asks embarrassing questions about private information that make many people unwilling to respond.

Response Bias Examples
Another example of response bias is when a person selects an answer to a question that they are aware is incorrect, but they make this choice because they are uncomfortable reporting their honest answer.
