Means Data Table

The Means data table is created after you select the Save Means option in the Response Screening red triangle menu. The data table contains a row for each combination of response and X level. For the Probe.jmp sample data table there are 387 response variables, each tested against Process at two levels. Therefore, the Means table contains 387x2 = 774 rows.
