Use Factorial Plots
to plot the relationships between the response and the variables.
- Use a main effects plot to display the relationship between the response and individual variables.
- Use an interaction plot to display how the relationship between one variable and a fitted response depends on the value of a second variable.
Use Cube Plot
when you have a two-level factorial design or a mixture design and you want to show the relationship between the factors and a response. Each cube can show three factors. If there are only two factors, Minitab displays a square plot. Minitab draws as many cubes as necessary to show up to eight factors. Center points are displayed only for designs with five or fewer factors. In a mixture design, cube plots can show the following:
- The combinations of factor settings and the data mean for each combination.
- The combinations of factor settings without any response means.
