A one-way ANOVA (Analysis of Variance) tests if three or more group means differ significantly. The null hypothesis states all group means are equal, while the alternative suggests at least one differs. It compares variance between groups to variance within groups, yielding an F-statistic. If F surpasses a critical threshold, we reject the null. For example, testing if different fertilizer treatments result in distinct mean plant heights uses ANOVA. This approach, a natural extension of the two-sample t-test, ensures an efficient evaluation of multiple categories simultaneously, common in experimental research and multifactor scenarios.
