2、什么是標(biāo)準(zhǔn)偏差？

標(biāo)準(zhǔn)偏差

標(biāo)準(zhǔn)差（Standard Deviation），是在概率統(tǒng)計(jì)中最常使用，作為統(tǒng)計(jì)分布程度（statistical dispersion）上的測(cè)量。標(biāo)準(zhǔn)差定義為方差的算術(shù)平方根，反映組內(nèi)個(gè)體間的離散程度。測(cè)量到分布程度的結(jié)果，原則上具有兩種性質(zhì)：一個(gè)總量的標(biāo)準(zhǔn)差或一個(gè)隨機(jī)變量的標(biāo)準(zhǔn)差，及一個(gè)子集合樣品數(shù)的標(biāo)準(zhǔn)差之間，有所差別，其公式如下所列。標(biāo)準(zhǔn)差的觀念是由卡爾·皮爾遜（Karl Pearson）引入到統(tǒng)計(jì)中。

公式

標(biāo)準(zhǔn)偏差公式：S = Sqrt[(∑(xi-x拔)^2) /（N-1）]公式中∑代表總和，x拔代表x的均值，^2代表二次方，Sqrt代表平方根。

STDEV基于樣本估算標(biāo)準(zhǔn)偏差。標(biāo)準(zhǔn)偏差反映數(shù)值相對(duì)于平均值(mean) 的離散程度。

其他定義

標(biāo)準(zhǔn)差也被稱為標(biāo)準(zhǔn)偏差，或者實(shí)驗(yàn)標(biāo)準(zhǔn)差，標(biāo)準(zhǔn)差(Standard Deviation)各數(shù)據(jù)偏離平均數(shù)的距離（離均差）的平均數(shù)，它是離差平方和平均后的方根。用σ表示。因此，標(biāo)準(zhǔn)差也是一種平均數(shù)。標(biāo)準(zhǔn)差是方差的算術(shù)平方根。　標(biāo)準(zhǔn)差能反映一個(gè)數(shù)據(jù)集的離散程度。平均數(shù)相同的，標(biāo)準(zhǔn)差未必相同。
