Specify further design information for Define Custom General Full Factorial Design

Stat > DOE > Factorial > Define Custom Factorial Design > Designs

You can specify the design columns that are already in the worksheet. If you do not have columns that contain the design information, then Minitab creates new columns.

Standard Order Column

If you do not specify a column, then Minitab creates a column that is the row order of the data. Standard order is also called Yates' order.

Order of the data: Select this option if no standard order column is in the worksheet or if the standard order is the order in the worksheet.
Specify by column: Select this option if the worksheet contains a column that identifies the standard order of the experimental runs.

Run Order Column

If you do not specify a column, then Minitab creates a column that is the row order of the data.

Order of the data: Select this option if no run order column is in the worksheet or if the experimental runs are in the order that they should be done.
Specify by column: Select this option if a column in the worksheet identifies the order that the experimental runs should be done.

Point Type Column

For a general full factorial design, Minitab Statistical Software does not use the point type column in the analysis of the design. If you have a point type column from a 2-level design that Minitab Statistical Software created, then you can specify that column with the design. Then, the point type information can be accurate if you redefine the design again. If you do not have a point type column, Minitab Statistical Software creates a column with 1 in every row.

Unknown: Select this option unless a point type column exists for a 2-level design that Minitab Statistical Software created.
Specify by column: Select this option if a point type column exists for a 2-level design that Minitab Statistical Software created.

Blocks

If you specify a column with multiple values, Minitab Statistical Software can include a term for blocks in the model. If you do not specify a column, then Minitab creates a column with 1 in every row. You can directly edit this new column to identify blocks after you define the design

No blocks: Select this option if no block column is in the worksheet or if the design has no blocks.
Specify by column: Select this option if a column in the worksheet identifies which runs are in each block.

In this worksheet, these columns provide more information about the design:

StdOrder: This column contains the standard order of the runs.
RunOrder: This column contains the order that the runs should be performed. In this worksheet, the order of the factor settings is randomized so the run order is not the standard order.
PtType: This column contains a 1 in every row.
Blocks: This column has 1 for the first block and 2 for the second block with respect to the standard order of the design. Because blocks are randomized, 2 precedes 1 in run order. All runs for the same block are contiguous in run order.
