That right there is the standard deviation to the right, that's the standard deviation to the left.

右边是右边的标准差，左边是标准差。

It has a standard deviation of 0.7 liters or 0.7 liters.

它的标准偏差为 0.7 升或 0.7 升。

Raymond, you were the one who scored one standard deviation higher than Debra.

雷蒙德，你的成绩应该比黛布拉高一个等级。

That's going to be the standard deviation of this.

这将是这个的标准偏差。

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。

The larger your n, the smaller a standard deviation.

n 越大，标准偏差越小。

So, in the trial we just did, my wacky distribution had a standard deviation of 9.3.

因此，在我们刚刚进行的试验中，我的古怪分布的标准差为 9.3。

And if you wanted the standard deviation of this distribution right here, you just take the square root of both sides.

如果你想要这个分布的标准偏差就在这里，你只需取两边的平方根。

So there's some standard deviation associated with this distribution.

所以这个分布有一些标准偏差。

So if we go back up over here, we calculated the standard deviation of this distribution to be 0.617.

所以如果我们回到这里，我们计算出这个分布的标准偏差为 0.617。

And if I want to figure out my sample standard deviation I just take the square root of that.

如果我想计算出我的样本标准偏差，我只需对其求平方根。

There's no radical sign, because we're not taking the standard deviation.

没有激进的迹象，因为我们没有采用标准偏差。

It's going to be that standard deviation divided by the square root of our sample size.

这将是标准偏差除以样本量的平方根。

And if you want the standard deviation, you can literally just get rid of this.

如果你想要标准差，你完全可以去掉它。

Oh, and if I want the standard deviation, I just take the square roots of both sides, and I get this formula.

哦，如果我想要标准偏差，我只需对两边取平方根， 就可以得到这个公式。

I'm just saying the standard deviation of that distribution.

我只是说该分布的标准偏差。

And so what is the probability that a random sampling mean is going to be two standard deviations?

那么随机抽样均值是两个标准差的概率是多少？

Or another way to view it is, this distance right here is going to be 1.65 standard deviations.

或者另一种看待它的方式是，这里的这个距离将是 1.65 个标准差。

So if we go 1 standard deviation to the right, that is going to be 1.

所以如果我们向右移动 1 个标准偏差，那就是 1。

And then the largest would be the standard deviation, d.

然后最大的是标准偏差 d。
