For the chi-square goodness of fit test to be valid, each of the expected cell frequencies should be at least 5. This ensures that the distribution being tested is not too skewed and that the test statistic follows the chi-square distribution. If any expected frequency is less than 5, the test may be unreliable and other tests should be considered, such as the Fisher exact test or the Monte Carlo simulation.
