标准差是方差的平方根。
标准差衡量色散、变异或扩散。
Standard deviation is a measure of dispersion, variation or spread.
但若组合里只有股票和债券,我的标准差会高得多。
But if I would confine myself just to stocks and bonds, then I would get a much higher standard deviation.
根据我的估算,那次波动偏离均值有25倍标准差之巨

不幸的是,度量漂移量很大;例如,标准差很容易增加到三倍。
Unfortunately, the measurement scatter is much higher; for example, the standard deviation could easily be three times larger.
不同研究所涉及香烟的物理特性的平均数和标准差。
Mean (SD) of physical characteristics of cigarettes from different studies.
研究人群中的平均依从率为96.3%(标准差,SD:7.7)。
The mean adherence rate in the study population was 96.3% (standard deviation, SD: 7.7).
然后,通过实例的考查,间接地估算了样本总体的相对标准差。
Then the relative standard difference is estimated indirectly from the research of the examples.
和前面的结局相同,你需要提供每组的参与者人数、结局的平均值和标准差。
As for the previous outcome, you will need to provide the number of participants, the mean outcome value and the standard deviation for each group.
接著利用统计的方法,建立出波包标准差以及各外加条件的模型。
And try to establish a model of standard deviation of wave packet by using statistical methods.
您可以利用此函数将您的样本方差计算转换为样本标准差计算,如清单8所示。
You can use it to turn your variance measurement into a standard deviation measurement, as shown in Listing 8.
对于连续性变量结局,你需要输入每组的参与者数目、结局的平均值和标准差。
For continuous outcomes, you will need to enter the number of participants, the mean outcome value and the standard deviation for each group.
它是帕雷托图表的基础,是一个用在全面质量控制和六标准差中的关键工具。
It is the basis for the Pareto diagram, one of the key tools used in total quality control and Six Sigma.
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.
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.
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.
使用收益的期望值—标准差无差异曲线与相应的效益函数来描述决策者不同的风险态度;
The indifference curves of expected values and standard deviations of net income are adopted to simulate the different risk attitudes of different decision-makers.
保单的数量并不影响其均值,但是会影响其标准差,所以这条曲线非常陡峭,而这就是保险的核心原理
Number of policies doesn't affect the means but it affects that standard deviation, so it becomes very collapsed and this is the basic core idea of insurance.
