Question

If we reject H0: μ1 = μ2 = μ3 in a one-way ANOVA (choose the correct one)

a. we conclude that μ1 ≠ μ2 and μ2 ≠ μ3

b. we conclude that μ1 ≠ μ2 ≠ μ3

c. the variation within samples is larger than the variation between samples

d. we conclude that at least one of the means is different

Answer 1

In a one-way ANOVA, if we reject the null hypothesis, it means that at least one of the means is different.

Step-by-step explanation:

In a one-way ANOVA, if we reject the null hypothesis, H0: μ1 = μ2 = μ3, it means that at least one of the means is different.

So the correct option is (d) we conclude that at least one of the means is different.
