So let's calculate the grand mean.

因此，让我们计算总均值。

And I'm actually going to call that the grand mean.

我实际上将其称为平均数。

Well, as an English person if you look at the phrase, you'd think " grand" means something really good, like, brilliant or fantastic, but actually in the Irish use it just means " fine" .

嗯，作为一个英国人， 如果你看这个短语，你会认为“grand” 的意思是非常好的， 比如，brilliant 或 fantastic， 但实际上在爱尔兰语中， 它只表示“fine” 。

So if you were to take the mean of the means, which is another way of viewing this grand mean, you have 2 plus 4 plus 6, which is 12, divided by 3 means here.

因此，如果你采用均值的均值，这是查看这个总均值的另一种方式， 你有 2 加 4 加 6， 即 12，在这里除以 3 均值。

Notice that we don't say " three grands" or " two grands." Even if it's plural, it just remains " grand." In this case, he's saying that the watch cost a couple of grand, meaning two or three thousand dollars.

请注意，我们不说“three grands” 或“two grands” 。 即使它是复数，它仍然只是“grand” 。 在这种情况下， 他说的是 watch cost a couple grand，意思是两三千美元.
