The chi-square statistic should not be used if the expected frequency for any cell is less than 5. This is because the chi-square distribution assumes that the expected frequencies are not too small. When the expected frequencies are very small, the distribution of the statistic deviates significantly from the chi-square distribution, which makes it unreliable.
