The probability of getting a more extreme result or Z score above that is 2.5%.

获得更极端结果或高于该结果的 Z 分数的概率为 2.5%。

This is actually called the standard z score.

这实际上称为标准 z 分数。

One thing I found in statistics is there's a lot of words a lot of definitions and they all sound very fancy, the standard z score.

我在统计中发现的一件事是有很多词很多定义而且它们听起来都很花哨，标准的 z 分数。

Let's say I had a probability distribution and I get some x value that's out here and it's 3 and a half the standard deviations is away from the mean, then it's standard z score is 3 and a half.

假设我有一个概率分布，我得到了一些 x 值，它是标准偏差偏离均值的 3 个半，那么它的标准 z 分数是 3 个半。
