Anova, Statistics.
ANOVA H₀ : µ₁=µ₂=µ₃ (implies that all 3 comes from same population) H₁: µ₁≠µₓ (at least one of the sample means is different from the rest of the sample means) REMEBER: We are not asking if “sample means” are EXACTLY equal. We are asking if each mean likely came from the larger overall population.
