Suppose, W U X the number of items for which the subject gives incorrect answers the number of items left unanswered by the subject, that is, the number of items that the subject does not reach the total error score Speed Test versus Power Test 41 Thus, X=W+U For a pure Speed Test, W will always be zero for each individual. Therefore, mean (M) and standard deviation (S) of ‘W’ will be zero. Mathematically, Mw = 0 Sw = 0 Also X = U, that is the individual total score will be found by the number of items that he does not answer.

On the other hand, if the temperature of the body is measured on the Kelvin scale, which is the true measure of kinetic energy of heat associated with the random motion of molecules of the substance, we can say that the body possesses four times the kinetic energy of heat or the motion of the molecule is four times as rapid at 40 degrees Kelvin as at 10 degrees Kelvin. We know that heat is the internal/kinetic energy which an object possesses because its molecules are in motion. At zero degree absolute Kelvin scale, it is a point at which matter ceases to agitate.
