我们知道,进行抽样调查的最终目的是通过调查所取得的样本资料来估计总体的估计值。在估计总体的估计值时,有时又离不开权数指标及权数,而可作为权数指标的具体指标又不止一个。因此,在抽样调查的估计总体的估计值时,一定要科学地选择与使用权数指标及权数。 We know that the ultimate goal of conducting a sample survey is to estimate the overall estimate from the sample data obtained from the survey. When estimating the overall estimate, sometimes there is more than one weight index and weight, but more than one index can be used as the weight index. Therefore, in the sample survey estimated the overall estimate, we must scientifically select and use the weights of indicators and weights.
