Similar to what we do in Chi-square test, the **fisher** option is used on the **tables** statement to obtain the test statistic and its associated p-value. The mpg data file was used and instead looking for the relationship between **cyl_six** and** d****rv_front**, the relationship between **cyl** and **drv** is what we interest in.

proc freq data = mpg; tables cyl * drv / fisher; run;

Since some of the cells have less than 5 expected count, Chi-square test may not have reliable result. The result of Fisher’s exact test suggest that there is a statistically significant relationship between **cyl** and **drv** (p = 6.816E-24).
