The null hypothesis in a one-way ANOVA test is that the population means are all equal and the alternative hypothesis is that there is a difference in the population means.
- Null hypothesis (H₀): All group means are equal (µ₁ = µ₂ = µ₃ = ... = µₙ).
- Alternative hypothesis (Hₐ): At least one group mean is different from the others.
