Standard deviation and sigma算法
請問關於Standard deviation(EXCEL裡的STDEV) 和 SIGMA算法的差異？！這..是一樣的東西嗎？！

By definition, they should be the same terms while standard deviation (sigma) is different from standard deviation (s):
A distinction is made between the standard deviation σ (sigma) of a whole population or of a random variable, and the standard deviation s of a subset-population sample.

Sigma (σ) 是希臘字元，表示為標準差 (Standard Deviation)的衡量。
