ANOVA (Analysis of Variance) requires the usage of the F-distribution.
The F-distribution is a probability distribution that arises frequently in statistical hypothesis testing, particularly in the context of comparing variances or testing the equality of means from multiple groups. In ANOVA, the F-statistic is calculated as the ratio of the variance among group means to the variance within the groups, and its distribution follows the F-distribution under certain assumptions.
By comparing the calculated F-statistic to critical values from the F-distribution, statisticians can determine whether the observed differences among group means are statistically significant or if they could have occurred by random chance. If the calculated F-statistic is greater than the critical value, one may reject the null hypothesis and conclude that there are significant differences among the group means.
