A true score is the actual amount of something that a person is attempting to measure. Consider measuring how fast an object is moving. One might say, “My car is moving at 55 miles-per-hour,” but 55 miles-per-hour is a relative assessment to some stationary position. Moreover, the Earth moves around the Sun, but the reported speed of the car does not consider the movement of the Earth around the Sun. Furthermore, Earth rotates on an axis; thus, any statement about how fast a car is moving does not consider the movement that is part of the rotational speed of the Earth on an axis. The introduction of relativity means that the idea of measuring the speed of a car is really a relative ...
