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 ANOVA finds that at least one group is different, perform a comparisons analysis 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.
