What we're going to do in this video is talk about the idea of a sampling distribution. Now, just to make things a little bit concrete, let's imagine that we have a population of some kind. Let's say it's a bunch of balls, each of them have a number written on it. For that population, we could calculate parameters. So a parameter you could view as a truth about that population. We've covered this in other videos. So for example, you could have the population mean, the mean of the numbers written on top of that ball.
