 Hi, this is Don. I just want to show you again how fast you can solve a contingency problem using StatCrunch. This is my StatLab. We're given this table. Got a link there. I'm going to open it in StatCrunch. So here we have our data. We go to Stat, Tables, Contingency with Summary because this is a summary. We select our column data. I'm going to click on Stretch. Help my shift down, not Stretch. My row labels result. I want expected counts. I'm going to go ahead and get the contingency or the chi-square test done too. And just click on Compute. I'm going to move this over here out of the way. You can see we have our answers there. It gave us the marginals, 232, 222, 454, 410, 44. And it gave us our expected 22.48 all the way down to 200.48. So remember that. Hope this helps.
