Squared divided by the expected. So we're essentially taking the square of, almost you could kind of view it, the error between what we observed and expected, or the difference between what we observed and expected. And we're kind of normalizing it by the expected right over here. But we want to take the sum of all of these. I'll just do all of those in yellow. Plus 14 minus 20 squared over 20. Plus 34 minus 30 squared over 30.
