The sample standard deviation , familiar to many from their statistics 101 class or black belt training , is basically the length of the variations vector 樣本的標準偏差,與統(tǒng)計101課程或6西格瑪培訓時一樣,主要是變量矢量的長度。
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準差和b類不確定度評定方法計算重復性引起的不確定度,使可以在符合檢定規(guī)程規(guī)定的較少測量次數(shù)中得到比較可靠的標準不確定度。
