Residuals Plots

This plot shows the scatter of residuals for the two different levels of temperature used in the experiment.  If one setting has a lower scatter than the other then it makes sense to set the process at that point, assuming it doesn't conflict with other factor settings.  Sometimes a factor will be found to have little effect on the operating point of the process, but a significant effect on the scatter of output values.
