# Can I partition a frequency table and use Fisher's exact test instead of the chi-squared test?

I am working with very small cell counts, and am wondering if Fisher's exact test can be used in place of the chi-squared test when partitioning IxJ tables. I am interested if the same process for partitioning the tables is acceptable.

You seem to be asking two questions:

1. Can Fisher's exact test be used for ixj tables?

The answer to 1 is easy: Yes it can. In SAS there is an EXACT statement in PROC FREQ. In R there is fisher.test in the stats package.
