英汉例句

• actually, a colleague and i recently discussed the importance of standard deviation and how it is often simply ignored.

  事实上，最近我和一个同事讨论了关于标準偏差的重要性，以及它常常被人忽视的情况。

• in the final section we showed by example that both the mean and standard deviation are less resistant to dispersion within a dataset.

  在最后的部分中，我们通过范例显示了中间值和标準偏差对于数据集内的分散度都没有多大的抵抗力。

• the difference between them is 13.61, which is almost one full standard deviation in the iq distribution (σ = 15).

  这之间的差是13.61，这差不多是智商分布中的一个标準偏差（=15)。

• also the calculations using non-distributive measures such as standard deviation will not produce reliable results if propagated to the virtual cube.

  如果将使用非分布式测度（比如标準偏差）的计算传播到虚拟数据集，将导致不可靠的结果。

• what the standard deviation really tells you is that some set of users were + or - the test average (or arithmetic mean).

  标準偏差真正能够告诉您的是，某些用户是高于还是低于平均测试水平（或者算术含义）。

• i mentioned standard deviation a few times above with regard to garbage collection, and this is something that is often overlooked when evaluating performance results.

  在前文中我多次提到关于垃圾收集的标準偏差，并且在评估性能结果的时候，人们常常会忽略它。

• however, there is a disadvantage of relying on the mean and / or the standard deviation as a measure of location.

  但是，依赖平均值和标準偏差作为位置的度量手段，有一个缺点。

• the other question to address is how reliable these mean and standard deviation statistics themselves are.

  要解决的另一个问题是，这些平均值和标準偏差统计值本身的可靠性如何。

• since this overhead is static, comparisons are valid and the typical uses of standard deviation in performance testing apply.

  因为该负荷是静态的，所以比较是有效的，而且性能测试应用中标準偏差的典型使用也是有效的。

• and you can calculate the standard deviation that way.

  你可以用这种方法计算标準偏差。

• compute confidence intervals for the mean and standard deviation to indicate how reliable they are.

  计算平均值和标準偏差的置信区间，以此表示这些数据的可靠性。

• how does the standard deviation quantify measurement scatter?

  标準偏差如何量化度量值漂移？

• not only have the averages decreased, but the standard deviation has decreased to below 1 second.

  不仅减少了平均值，还将标準偏差减少到了1秒钟以下。

• if there's a large standard deviation it would be spread.

  如果标準偏差值很大,那么它就比较分散。

• an eight standard deviation event happens once out of every six trillion trials.

  而八个标準差的偏离就意味着,六万亿分之一的概率

• this is important, because it shows that looking at just the average is not enough, especially if your standard deviation is a large number.

  这是很重要的，因为它说明了，仅查看平均值是不够的，特别是当您的标準偏差非常大的时候。

• there is no doubt that both the mean and standard deviation are effected by the presence of outliers, while the median and iqr are much less impacted.

  几乎不用怀疑平均值和标準偏差会收到异常值存在的影响，而中间值和iqr所受到的影响则较小。

• generational garbage collectors offer relatively short average gc pauses, but the cost of old-space collections can cause the standard deviation of these pause times to be quite large.

  分代垃圾收集器提供了相对较短的平均gc暂停时间，但是旧空间收集的开销可能导致这些暂停时间的标準偏差非常大。

• thus, if outliers are present within the dataset the mean and standard deviation are located accordingly.

  因此，如果在数据集内存在异常值的话，那么度量值和标準偏差会得到相应的定位。

• 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的标準偏差之内。

• if you look at the standard deviation of 796 milliseconds, the users may not be as happy as the average would predict.

  但是，如果注意到796毫秒的标準偏差，用户就不会像一开始看到这个平均响应时间那么高兴了。

• so, how can the mean and standard deviation be used to determine which of two tasks is faster?

  那么，如何用平均值和标準偏差判断两个任务中哪一个更快呢？
