The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1
<h3>What is the Correct Scale Calibration?</h3>
We are told that a certain scale is not calibrated correctly,
Mass displayed = 0.75 kg (less than its actual mass).
The scale of display = 1
Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.
Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.
