# Obtaining Exact Tests

- From the menus choose:
or

- In the dialog box, select Exact.
- Select a method for calculating significance.

- If you have selected the Monte Carlo method, enter a value for the confidence level, and specify the number of samples used in approximating the Monte Carlo approximation. If you want to duplicate your results, you should set the random number seed every time you use the Monte Carlo method. Monte Carlo results can be obtained more quickly than exact results.
- If you have selected the Exact method, enter the maximum time limit for calculating each test. If a test exceeds a set time limit of 30 minutes, it is recommended that you use the Monte Carlo method. If you find that you have insufficient memory to obtain exact results, you should first close any other applications that are currently running in order to make more memory available. You can also enlarge the size of your swap file. If you still cannot obtain exact results, use the Monte Carlo method.
