Three folks had their right hand longer but their left foot was longer. And then eight folks had their right hand longer but both feet were the same. Likewise, we had nine people where their left foot and hand was longer, but you had two people where the left hand was longer but the right foot was longer. And we could go through all of these. But to do our chi-squared test, we would have said what would be the expected value of each of these data points if we assumed that the null hypothesis was true, that there was no association between foot and hand length. So to help us do that, I'm gonna make a total of our columns here and also a total of our rows here. Let me draw a line here so we know what is going on.
