Select Help > Sample Data Library and open Popcorn.jmp.
Figure 4.13 Effect Summary Report
In the Effect Summary report, notice that the popcorn*batch interaction has a small p-value (0.00261). From this, you conclude that there is a significant interaction between popcorn and batch.
3.
Click the Response yield red triangle and select Save Columns > Prediction Formula.
4.
Click the Response yield red triangle and select Save Columns > Mean Confidence Interval.
This adds two new columns to the data table: Lower 95% Mean yield and Upper 95% Mean yield.
5.
Select Graph > Graph Builder.
7.
Select popcorn and drag it to the X zone.
8.
Select batch and drag it to the Group X zone.
9.
Select oil amt and drag it to the Group Y zone.
Figure 4.14 Yield Values for the Eight Factor Combinations
Format the graph to see interval bars for Lower 95% Mean yield and Upper 95% Mean yield, and to see points for Pred Formula yield.

12.
In the Bar options panel, select Interval from the Bar Style menu. See Figure 4.15.
Figure 4.16 Interval Bar Style Applied to Three-Y-Axis Variables
The interval bar style currently spans from Lower 95% Mean yield to Pred Formula yield, but you want it to span up to Upper 95% Mean yield. Remove the bar element for Pred Formula yield.
Figure 4.17 Interval Span for Confidence Boundaries
Remove the point graph element for Lower 95% Mean yield and Upper 95% Mean yield.
14.
In the Points options under Variables, deselect Y Lower 95% Mean yield and Y Upper 95% Mean yield. See Figure 4.17.
Figure 4.18 Predicted Means and Confidence Intervals
From Figure 4.18, you can see the following relationships:
