The question is about the ANOVA (Analysis of Variance) procedure. ANOVA is a statistical method used to determine if there are significant differences between the means of three or more groups (or populations). Specifically, ANOVA tests whether the means of different populations are equal or not.

In this case, the correct answer to the question, "The ANOVA procedure is a statistical approach for determining whether or not...":

The correct choice is:

• "the means of more than two populations are not equal."

ANOVA's main purpose is to test if the means of multiple groups (populations) are equal. If the means are not equal, it indicates that at least one group is different from the others.

3. What are the assumptions needed for ANOVA?
4. Can ANOVA be used for two groups, or is it strictly for three or more?
5. What is the difference between one-way and two-way ANOVA?

Tip: When using ANOVA, it's essential to ensure that the populations you're comparing have similar variances (homogeneity of variance) and that the samples are independent.
