Defining Factors and Responses

The Die Cast design is an example where this technique has been used. Here, however, you re-create the design so you can learn how to define the variables for a Plackett-Burman Design by following these steps:

1. Select File Create New Design Two-level from the ADX desktop to open the main design window.
2. Click Define Variables.
3. Click Add and select 8 as the number of rows to add. ADX adds one row for each factor and automatically fills in the coded levels for each of the factors.
4. Type a Factor Name, Low Level, High Level, and Factor Label for each factor as in Table 5.1
5. In a similar fashion click the Response tab to enter one response variable.
6. Click OK to save the changes.
