Well, all we need to do is find the distance from each of these points to our mean right over here, and then square them and then take the mean of those squared distances. So let's do that. So it's going to be 4 minus 4.6 squared plus 4.2 minus 4.6 squared plus 5 minus 4.6 squared plus 4.3 minus 4.6 squared. And then finally, I'm running out of space, plus 5.5 minus 4.6 squared. And then we're going to divide all of that by 5 to get our population variance. And so what's that going to give us? Let's get our calculator out.
