The sample standard deviation , familiar to many from their statistics 101 class or black belt training , is basically the length of the variations vector 樣本的標(biāo)準(zhǔn)偏差,與統(tǒng)計(jì)101課程或6西格瑪培訓(xùn)時(shí)一樣,主要是變量矢量的長(zhǎng)度。
Using the method of merging sample standard deviation and evaluating indeterminacy of category b to calculate the indeterminacy aroused by repetitiveness can obtain reliable standard indeterminacy in much less time tallied with the inspection procedure 論述采用合并樣本標(biāo)準(zhǔn)差和b類不確定度評(píng)定方法計(jì)算重復(fù)性引起的不確定度,使可以在符合檢定規(guī)程規(guī)定的較少測(cè)量次數(shù)中得到比較可靠的標(biāo)準(zhǔn)不確定度。
