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. It looks like in general, the more computer time, the higher the blood pressure, or the higher the blood pressure, the more computer time. And so you can make a conclusion here about these two variables correlating, that they're positively correlated. There is a positive, a reasonable conclusion, if you did the study appropriately, would be that more computer time correlates with higher blood pressure, or that higher blood pressure correlates with more computer time.
