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

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

使用这些统计数据判断是否可以清楚地区分两个任务的速度(平均值之差超过三倍标准偏差)，还是相互重叠。

Use these statistics to decide that two tasks are either clearly distinguished in speed (means greater than three standard deviations apart), or else that they overlap.

使用平均值和标准偏差，您可以说明，68% 的尝试是在 0.2 秒到 1.3 秒之间。

Using the average and the standard deviation, you can interpret that 68% of the attempts were between .2 and 1.3 seconds.

And then I could also do a Gaussian one here, with the mean of and the standard deviation of volatility divided by 2.

然后我在这里再写一个高斯分布的函数，它的浮动值的平均值和,标准偏差值都除了2。
