One of the goals of all statistical work is the estimation of key features of the measurement of interest in the target population. An example of such a feature might be median household income, or perhaps the proportion of the adult population that suffers from diabetes. These estimates can be expressed either as a specific value (a point estimate) or a range of plausible values (an interval estimate). The spread of an interval estimate reflects the uncertainty with which the feature can be estimated using information obtained by sampling units from the target population, and measuring the feature on the units in the sample.

所有统计工作的目标之一是估计目标人口中感兴趣的计量的关键特征。 这种特征的一个例子可能是家庭收入中位数，或者可能是成年人口中患有糖尿病的比例。 这些估计值可以表示为特定值（点估计）或合理值的范围（区间估计）。 区间估计的扩展反映了使用从目标总体中采样单元并测量样本中单元的特征所获得的信息来估计特征的不确定性。
