Experimental values are close but are not equal to the factor values in outlined in the DoE.
In my class, students use custom design to plan their experiment. They conduct trials targeting the factor values recommended by JMP. In practice, the conditions of the experiment are a little different for a variety of reasons. I recommend they input the "actual/measured" values when analyzing the results? Am I correct? How does this affect their analyses as the conditions may not be orthogonal a...
