So for example, let's say, and I wouldn't, if you're actually trying to do this, I would recommend doing at least 100 data points, or 1,000, and later on we'll talk about how you can think about whether you've measured enough, or how confident you can be. But let's just say you're a little bit lazy, and you just sample five men. And so you get their five heights. Let's say one is 6.2 feet. Let's say one is 5.5 feet. 5.5 feet would be five foot six inches. One would be, let's say one ends up being 5.75, seven five feet.
