When expected frequencies are smaller than five, one way to correct for it is to increase the levels of the categorical variable to ensure that no expected frequency is less than five. This can be achieved by merging categories or grouping data into larger categories. However, the new number of levels should not be too large, or it may lead to loss of information and statistical power. Therefore, increasing the number of levels to greater than four is a reasonable choice.
