Key-in Your X,Y List

The XY List is your data. When it is complete, it will contain all of the factor settings and response measurements for each run in the experiment.

Enter a unique file name for your design. This file will be stored in the Strategy\Designs directory.

Enter the number of columns in your data. You will have a column for each factor (X) and one for each response (Y).

A RUNORD column will be provided for run order. We strongly recommend recording the run order used to aid in the analysis. Do not count the run order column when calculating the number of columns.

If you did not use the designed run order, check no in response to the question: “Would you like the run order to be 1, 2, 3, 4. . . ?” Enter the run order you actually used. In the analysis you will see if changes occurred in parallel with run order.

You will be making as many rows as you made runs in the experiment.

When you have named your file, set the number of columns, and specified the number of rows that you will need, you can click the OK button to start entering your data. The Strategy Spreadsheet should appear with the Column Name dialog box positioned in front of it.

Enter the appropriate name for each column as prompted by the dialog box, and you are ready to enter the data in the spreadsheet.

The first column must be the run order in which the trials were run.

If you DID NOT scramble your runs your b’s might be contaminated by extraneous factors. Enter the run order you used, but remember that the scatter plot of residuals versus run order will be of little use to you if you did not use a scrambled run order.

The X columns are for factors which are the directly controllable settings in your experiment. The Y’s are responses which are the output performance measurements.

A template is provided on the screen to enter your run order, factor levels and responses. The observation numbers are shown. Use the TAB or RETURN keys to move from field to field in a column.
