Allows you to name or rename the factors and assign values for factor settings. Allows you to name or rename the signal factor and assign values for the signal factor setting. You can assign factors to array columns yourself. Or, you can ask Minitab to assign factors to array columns to allow for the estimation of interactions you select.
Assign Factors:
To columns of the array as specified below: Choose to assign factors to columns of the orthogonal array. Assigning factors to columns of the array does not change how the design appears in the worksheet. For example, if you assigned Factor A to Column 3 of the array and Factor B to Column 2 of the array, Factor A would still appear in Column 1 in the worksheet and Factor B would still appear in Column 2 in the worksheet.
To allow estimation of selected Interactions: Choose to have Minitab automatically assign factors to array columns in order to allow the estimation of selected interactions.
Factor: Shows the number of factors that you have chosen for your design. This column does not take any input.
Name: Enter text to change the name of the factors. By default, Minitab names the factors alphabetically.
Level Values: Enter numeric or text values for each level of the factor. By default, Minitab sets the levels of a factor to the integers 1, 2, 3, ...
Column: Enter the column of the array that you want to assign the factor to.
Levels: Shows the number of levels for each factor. This column does not take any input.
Signal Factor:
Name: Enter text to change the name of the signal factor. By default, Minitab names it "Signal."
Level Values: Enter numeric values for each level of the factor.
