Sigma σ is a Greek letter used in mathematical statistics to represent the standard deviation of a distribution σ 是希臘字母 , 用於統(tǒng)計數(shù)學(xué) , 代表統(tǒng)計學(xué)中 的標(biāo)準(zhǔn)偏差 S = ( X X ) 2 n 1 n i=1 i Site: Multek Asia Site : Sigma σ is a measure of the amount of variability that exists when we measure something. In the case of a product, we usually have many characteristics important or critical to quality. σ是我們量度某些東西所存在之差異量的一種量度方式 In the case of a product, we usually have many characteristics important or critical to quality. We usually collect data and measure the sigma of some of these characteristics. 在產(chǎn)品來說 , 我們通常有許多特性是對品質(zhì)非常重要或 關(guān)鍵性的 除了公式以外 , Sigma σ是 甚 麼 ? Site: Multek Asia Site : If the sigma value is large it tells us there is a lot of variability in the product. 如果 σ值是大 , 則表示產(chǎn)品內(nèi)之差異非常大 . If the sigma value is small, then the product has very little variability and thus, very uniform. 如果 σ值是小 , 則表示產(chǎn)品內(nèi)之差異不大 , 非常一致 . Sigma σ值代表甚麼 ?
