Well, we just have to add all of these data points up and divide by 5. And I'll just get the calculator out just so it's a little bit quicker. And so this is going to be 4 plus 4.2 plus 5 plus 4.3 plus 5.5. And then I'm going to take that sum and then divide by 5. And I get an arithmetic mean for my population of 4.6. So that's fine. And if we want to put some units there, it's 4.6 meters.
