Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects fail to respond during a survey. Hence, a likely scenario is ; surveys were mailed to 500 people, and 200 of the surveys were completed and returned.

Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.

If 200 surveys were returned, then 300 of the sample participants did not respond. Which means 60% of the sample are non-responsive.

Therefore, a scenario where surveys were mailed to 500 people, and 200 of the surveys were completed and returned exemplifies a non - response bias.
