End of story. Oh, but I can fin an example where the average machines' performance differs, no problemo. Then, another (last, I hope) example :
We made a separate study on the same panel, which allowed us to conclude that : - Half of the audience, clearly prefers Cafemart cofee 100% of the time. They are never inconsistent. The factors of their preferences are unknown. - The other half, clearly prefers Caffefile 100% of the time. The factors of their preferences are equally unknown. Both audiences claim they prefer Caffefile cofee under any circumstances, and that Caffefile coffee is superior to the Cafemart one. We can conclude from this test, that half of the panel had probably never tasted Cafemart coffee before, and that it was probably mislead. The other half, they know what they prefer and why. In both cases we don't know why. Good. Let's see now which conclusions can we draw from the other test ?
