If the assumptions of the chi-square test cannot be met, Fisher's exact test can be used as an alternative. This test can be used when the sample sizes are small or when one or more expected cell frequencies are less than 5. The test is based on the exact probabilities of observing the observed data or more extreme data if the null hypothesis is true. In contrast, chi-square relies on an approximation of the distribution of the test statistic.
