ヾ(?°?°?)??你好同學(xué),
The sampling error is best described as the difference between the observed value of a statistic and the quantity it is intended to estimate.
題目和B連起來
The sampling error is best described as the difference
抽樣誤差=差值
between the observed value of a statistic and the quantity it is intended to estimate.
在“統(tǒng)計的觀測值”和“要估計的數(shù)量”
例如:
樣本均值(統(tǒng)計的觀測值)和總體均值(要估計的數(shù)量)的差值就是sampling error
