Overview for Main Effects Plot

Use Main Effects Plot to see how one or more categorical factors influence the continuous response.

For example, a carpet manufacturer wants to see the results for a one-way ANOVA. The manufacturer creates a main effect plot of the average carpet durability scores by carpet type.

Where to find this analysis

To create a main effects plot, choose Stat > ANOVA > Main Effects Plot.

When to use an alternate plot

This plot displays data means. After you fit a general linear model, you can use factorial plots to create main effects plots and interaction plots that have fitted means instead of data means.
