| bias |
The extent to which a measurement, sampling, or analytic method systematically underestimates or overestimates the true value of an attribute. FOR EXAMPLE, words, sentence structure, attitudes, and mannerisms may unfairly influence a respondent's answer to a question. Bias in questionnaire data can stem from a variety of other factors, including choice of words, sentence structure, and the sequence of questions.

| biased sample |
A sample that is not representative of the population to which generalizations are to be made. FOR EXAMPLE, a group of band students would not be representative of all students at the middle school, and thus would constitute a biased sample if the intent was to generalize to all middle school students.
