测量是指偏离真正的测量值作为适用于样本单位和提供价值。可以被认为是一个例子关于药物使用和健康调查的问题(NSDUH)要求被申请人是否他有,甚至有一次,已采取任何形式的可卡因。结果常见相关行为被视为不受欢迎的和可能会低估了。因此,可以有一个缺口的真正价值的回应,这是“是”,但被申请人回答“不”为避免他人学习的潜在崩溃的使用药物。
这种行为与这样的回答是政府频繁和常规问题。这导致真正的样本均值之间的差异和被调查者平均响应。会有低估的比例的人报告了可卡因的终身使用上面的示例。符号的统计数据,引入一个新的术语表示的响应问题是独特的不同于真实价值的衡量,Y,的人。易建联的响应问题是表示的系统偏差值作为(易建联,易建联)。

The measurement means a departure from a true measurement value as applicable in a sample unit and the provision of the value. An example can be considered regarding a question of National Survey on Drug Use and Health (NSDUH) asking the respondent whether he has, even once, has taken any form of cocaine. The findings that are common are related to the behaviour being perceived as undesirable and are likely to be underreported. Thus, there can be a gap with respect to the true value of the response, which is “yes”, but the respondent answering “no” for the avoidance of the potential discomfiture of others learning of his use of drugs.
These kind of behaviour related to such responses is frequent and regular across the question’s administration. This results in a discrepancy between the true sample mean and the respondent mean response. There will be underestimation of percentage of persons that has reported the lifetime use of cocaine in the example provided above. In the notation of statistics, the introduction of a new term denoting the response to the question is distinctively different from the true value of the measure, Y, for the person. The response to the question yi is denoting of the systematic deviation from the values as (yi – Yi).
