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. So I can literally create my own custom distribution here. So let me make something kind of crazy. So you could do this, in theory, with a discrete or a continuous probability density function.
