The chi-square statistic should not be used if the expected frequency (fe) in any cell is less than 5. This is because the chi-square test assumes that the expected frequencies should be reasonably close to the observed frequencies in order for the test to be valid. If the expected frequency is too low, the test becomes unreliable and may not accurately reflect the true population.
