How I calculate the chi-square coefficient on a contingency table?
I have a table with the frequencies of liking of an item under certain condition. I need to calculate on this data the chi-square because I need it to calculate the association index of Cramér. How can I calculate the chi-square coefficient? Thanks.

Do you have the Statistics Toolbox? If so, then use crosstab() that will produce a contingency table and optionally output a chi-square statistic.
If you do not have the Statistics Toolbox, search the file exchange for contingency table.

Just taking a quick look, I see that there appear to be routines that use Fisher's exact test that don't have Statistics Toolbox listed as a required product. Would Fisher's exact test suffice?
