I'm currently running a course in ANOVA, and a question has arisen regarding x^2 tests. I know that Contigency tests operate for nominal X and nominal Y data counts, and observed values are in the data table--but I can't seem to find out how to set the expected values. JMP appears to set them as a computation from row counts, column counts, and a grand total--but I'd just like to set them to 1:1? Or do I establish another data column of expected values?
Thanks.
