Nonsampling errors describe reasons why our sample results may not reflect the actual population results for reasons other than bad sampling techniques. Examples of sources of nonsampling errors include:

· Wording of a question can make us respond to that question differently.

· Order of questions asked to a respondent can influence the way they respond to the question.

· “Social desirability” can influence how one responds to a question. This can be impacted by how the question is worded, who is asking the question, or even the demeanor of the interviewer.

· Sometimes the type of question asked might cause a respondent to answer untruthfully. If your truthful answer incriminates you morally or under the law, you may just lie when answering the question.

· Measurement error/tuning instruments
