Note that while we are unable to use the chi-square test for independence, we can use Fisher’s Exact Test. This test can be done on a [latex]2 \times 2[/latex] contingency table when the expected frequencies do not meet the conditions for the chi-square test.
For Fisher’s Exact Test, we require a simple random sample from the population and two categorical variables, each with two possible values. This will result in a [latex]2 \times 2[/latex] contingency table.
