WebFisher’s exact test is a nonparametric statistical test used to test the null hypothesis that no nonrandom associations exist between two categorical variables, against the alternative that there is a nonrandom association between the variables. WebOne major drawback of Fisher's exact test is that for large tables (or large samples) it becomes computationally ineffective. G-test Another alternative is the so-called G-test. Its statistic is also approximately chi-squared distributed, but for small samples, this approximation is closer than one that chi-squared test uses.
