Fisher's exact test is a suitable alternative to the chi-square test when the sample size is small, and the expected frequencies in one or more cells of the contingency table are less than 5. This occurs when the sample size is small or when the effect size is large. If the sample size is large, the chi-square test is an appropriate choice as it provides a reliable approximation even if the expected frequencies are less than 5. Choice A is incorrect because the chi-square test is suitable for large samples. Choice B is incorrect because the computation time of SPSS does not determine the appropriateness of the statistical test.
