# Chi-squared test not meeting assumptions

I am doing a chi-squared test to compare two treatment groups for any baseline differences eg gender, ethnicity etc. Most of these are 2x2 but ethnicity has at least 5 categories.

In several instances, the assumptions are not met, i.e. cells have counts smaller than 5 in them.

Therefore which test would I use rather than a chi-squared? Please remember that some of the tables are 2x3 or even 2x5.

• No, you appear to be doing a chi-squared test (or chi-square test). I'll edit – Glen_b Nov 10 '15 at 15:06

Recall that the assumption is that each cell has an expected count of at least 5. (The expected count in each cell is $\frac{\text{row total}\times\text{column total}}{\text{table total}}$.)
