一, 一般步骤
(1),消除或减小恒定系差
(2),求测量数据的数学期望 ,即算术平均值 :
, 其中n为测量数据次数, 为第 次测量的数据。
(3),求剩余误差 :
(4),根据贝塞尔公式求标准偏差 :
(5),检查是否有粗大误差。检查时用了肖维纳准则。如果某次测量的结果 所对应的 ,则认为是坏值,予以剔除。
(6),如有坏值,剔除后重新进行步骤(2)~(5)的计算,直至无坏值为止。
(7),判断有无变值系差。判断是可用马利科夫准则或阿卑—赫梅特准则。
(8),求出算术平均值的标准偏差 :
必须注意,如前面计算中曾出现坏值,则这里的 应为剔除后重新计算出的标准偏差。
(9),求算术平均值的不确定度
