为了计算我们财富的期望效用，你可能也得关注期望回报、或几何期望回报、或标准差。
To calculate the expected utility of your wealth, you might also have to look at the expected return, or the geometric expected return, or the standard deviation.
标准差衡量色散、变异或扩散。
Standard deviation is a measure of dispersion, variation or spread.
分析规程的精密度通常以一系列测量数值的标准差或相对标准差(变异系数)来表示。
The precision of an analytical procedure is usually expressed as the standard deviation or relative standard deviation (coefficient of variation) of a series of measurements.
在过程能力分析中通常采用子样级差或样本总体标准差来估计总体标准差。
The standard deviation in Process Capability Index(PCI) is estimated by using the subgroup ranges or the sample standard deviation.
结果各种溶液测定的总标准差小于其浓度的5 %或检出限，总平均回收率可信限在允许范围内。
Results Total standard deviation of every solution was less than 5% of the concentration or detection limit. The confident limit of total average rate of recovery in sample kept in range of allowable.
例如，可能需要自常态分配数量之产生样本或需要计算大量资料的标准差或绘制直方图。
For example, one may need to generate samples drawn from a normally distributed population or may need to compute the standard deviation of a large data set or plot a histogram.
两个模拟输入可以配置成两个单端输入，一个标准差分输入（对）或一个准差分输入。
The two analog inputs can be configured as two single-ended inputs, one true differential input pair, or one pseudo differential input.
