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

我实际上将其称为平均数。

So let's calculate the grand mean.

因此，让我们计算总均值。

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.
