So what is the total squared error with the line?

那么这条线的总平方误差是多少？

So are squared error versus our line, our total squared error, we just computed to be 2.74.

平方误差与我们的线，我们的总平方误差，我们刚刚计算为 2.74。

This is the total error, this is the total variation of the numbers.

这是总误差，这是数字的总变异。

And so what we calculated next was the total error, the squared error, from the means of our y values.

所以我们接下来计算的是总误差，平方误差，来自我们的 y 值的平均值。

And if you took take this total error, you can figure out the probability of getting that total error if you assume some parameters.

如果你考虑这个总误差，你可以计算出在假设一些参数的情况下得到这个总误差的概率。
