Overview for One-Way ANOVA

Use One-Way ANOVA when you have a categorical factor and a continuous response and want to determine whether the population means of two or more groups differ. If the test finds that at least one group is different, use the Comparisons dialog in one-way ANOVA to identify pairs of groups that are significantly different.

For example, a carpet manufacturer wants to determine whether there are differences in durability among several types of carpet.
