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.

For more information about the types of means, go to Data and fitted means.
