ヾ(◍°∇°◍)ノ゙你好同学,
The sampling error is best described as the difference between the observed value of a statistic and the quantity it is intended to estimate.
题目和B连起来
The sampling error is best described as the difference
抽样误差=差值
between the observed value of a statistic and the quantity it is intended to estimate.
在“统计的观测值”和“要估计的数量”
例如:
样本均值(统计的观测值)和总体均值(要估计的数量)的差值就是sampling error
