The critical variable was the standard deviation of the means divided by the mean of the standard deviations.

关键变量是均值的标准差除以标准差的均值。

And some people think, what's the probability that I land within one standard deviation of the mean?

有些人会想，我落在均值一个标准差范围内的概率是多少？

So it's literally what is the probability of finding a sample within two standard deviations of the mean?

所以从字面上看，在均值的两个标准差范围内找到样本的概率是多少？

So they're essentially asking us what's the probability of getting a result within two standard deviations of the mean.

所以他们本质上是在问我们在平均值的两个标准差范围内得到结果的概率是多少。

So 68.3%, and that's actually always the case that you have a 68.3% probability of landing within one standard deviation of the mean, assuming you have a normal distribution.

所以 68.3%，实际上总是这样， 假设你有一个正态分布， 你有 68. 3% 的概率落在均值的一个标准偏差内。

And it would be-- you could guess-- 68%, 68% chance you're going to get something within one standard deviation of the mean, either a standard deviation below or above or anywhere in between.

这将是——你可能会猜到——68%，68% 的机会你会得到在平均值一个标准偏差范围内的东西， 或者低于或高于标准偏差或介于两者之间的任何标准偏差。
