So let's say that there's one person who doesn't spend a lot of time on a computer, and they have a relatively low blood pressure. There's another person who spends a lot of time, has high blood pressure. There could be someone who doesn't spend much time on a computer, but has a reasonably high blood pressure. But you keep doing this, and you get all these data points for those 1,000 people. And I'm not going to sit here and draw 1,000 points. But you see something like this. And so you see, hey look, it looks like, there's definitely some outliers, but it looks like these two variables move together.
