One-way ANOVA (analysis of variance) is a technique that generalizes the two-sample t-test to three or more samples. We test the hypotheses (specified here for k=6 samples) about population means μ j : H 0:μ 1=μ 2=μ 3=μ 4=μ 5=μ 6 H 1: Not all μ j are equal (j=1:6) The test is based on the observed sample means \(\bar x_j\).
