So that's what it's called. And just as a little bit of background, and I'll prove this to you experimentally, not mathematically, but I think the experimental is, on some levels, more satisfying with statistics, that this will have the same mean as your original distribution right here. So it has the same mean, but we'll see in the next video that this is actually going to start approximating a normal distribution, even though my original distribution that this is kind of generated from is completely non-normal. So let's do that with this app right here. And just to give proper credit where credit is due, I think it was developed at Rice University. This is from onlinestatbook.com. This is their app, which I think is a really neat app, because it really helps you to visualize what a sampling distribution of the sample mean is.
