And to do that, we do it very similar to what we did with the restaurant situation. We figure out, assuming the null hypothesis, the expected results you would have gotten in each of these cells. You can view each of these entries as a cell. That's what we do with it. You call each of those entries in Excel also a cell, each of the entries in a table. What we do is we figure out what the expected value would have been if you do assume the null hypothesis. Then we find the squared distance from that expected value, and we, I guess you could call it, normalize it by the expected value, take the sum of all of those differences.
