This is the mean of our sample means. It's gonna be the same thing as that, especially if we do the trial over and over again. But anyway, the point of this video, is there any way to figure out this variance, given the variance of the original distribution and your N? And it turns out there is. And I'm not gonna do a proof here. I really wanna give you the intuition of it. And I think you already do have the sense that every trial you take, if you take 100, you're much more likely, when you average those out, to get close to the true mean than if you took an N of two or an N of five.
