The recommended guideline is to ensure that the expected frequency of each cell is at least 5. This is to ensure that the chi-square test statistic follows the chi-square distribution, which assumes that the expected frequency in each cell is not too small. Therefore, the lowest expected frequency is the key factor in determining whether the sample size is large enough for the chi-square test to be valid.
