TABLE OF CONTENTS

Step 1: Definition

The statistical approach of analysis of variance, or ANOVA, divides observed variance data into multiple components for use in additional tests. For three or more groups of data, a one-way ANOVA is used to learn more about the relationship between the dependent and independent variables.

Step 2: Explanation

The analysis of variance (ANOVA) method compares several population means, or the mean of a single variable over multiple populations.

It compares the means of two variables for populations that have been classified by a third variable.
