Normally distributed data assumes that about 68% of the values in the sample are within 1 standard deviation of the mean.
正态分布数据认为,样本中约68%的数值分布在距离平均值为1的标准偏差之内。
By using the sample mean range( R )instead of standard deviation of the sample( S )in"S " method, the"R " method is obtained in this paper.
在“S”法的基础上,利用样本平均极差R代替“S”法中的样本标准差S ,从而得到了“R”法,并且给出了相应的样本大小,及各种情况下的接收标准。
