So we're starting with the tongue in the middle area of the mouth.

一开始，舌头放在嘴巴中央。

And that includes this middle area right here.

这包括这里的中间区域。

It's right there, so it's 68%, which is this middle area within 1 standard deviation, plus this left branch right there.

它就在那里， 所以它是 68%，这是 1 个标准偏差内的中间区域， 加上这个左边的分支。

Those born in Britain to immigrant parents " occupy a gray, middle area, constantly changing, " he says, finding difficulty separating " the individual from the institution."

他说，那些出生在英国的移民父母“占据了一个灰色的中间区域地带，不断变化，”他发现很难将“个人与制度分开”。

So the empirical rule tells us that this middle area between 1 standard deviation to the left and 1 standard deviation to the right, that right there is 68%.

所以经验法则告诉我们，这个中间区域在左边 1 个标准差和右边 1 个标准差之间，右边有 68%。
