The extraction factors and their settings are given in the data table Extraction Factors.jmp. Generate a definitive screening design with a block as follows.
|
1.
|
Select DOE > Definitive Screening > Definitive Screening Design.

Click Continue.
|
|
6.
|
Select Add Blocks with Center Runs to Estimate Quadratic Effects.
|
Leave Number of Blocks set at 2.
You are recreating the design for the Extraction2 Data.jmp sample data table, which was created without Extra Runs. Although four Extra Runs are strongly recommended, you will not add Extra Runs in this example.
|
7.
|
Next to Number of Extra Runs, select 0.
|
|
8.
|
Click Make Design.
|
Check that Block has been added to the Factors outline and to the Design.
|

|
|
10.
|
Click Make Table.
|
At this point, you conduct your experiment and record your data in the Yield column of the design table (Figure 6.8). The Extraction2 Data.jmp sample data table contains your experimental results. The runs in the Extraction2 Data.jmp sample data table are in a different order than those in Figure 6.8.
