Let's say I collect data from an experiment where for each measurement device, 5 trials are conducted at different temperatures. Each device is calibrated separately, and the 5 trial temperatures are constant across devices. In other words, I have values at Temperature 1, 2, 3, 4, and 5 from each device.
What is an appropriate test to see whether the values from a given measurement device, adjusted for calibration, are significantly different from the other measurement devices? My guess is that the test must be conducted on the differences between the trial values to compensate for the different calibrations.
