Does a RAD measure accuracy or precision? Explain
Homework Answers
Accuracy of a dataset indicates the closeness of the measured values with standard value.
Precision defines the closeness of the measured values with each other.
Relative average deviation (RAD) is equal to mean deviation divided by arithmetic mean. It indicates how much the measured values differs from the arithmetic mean. So, it actually indicated the closeness of the measured values with each other. So, RAD actually measures precision.

Accuracy and Precision. Trooper Watkins uses a measuring wheel (image at right) to measure the distances involved in traffic accidents. One rotation of the wheel is supposed to be 36 inches, but it is really only 35 7/8 inches. Trooper Watkins’ new digital measuring wheel has an LED that gives reading to a tenth of an inch. His old mechanical measuring wheel, which was also supposed to be 36” in circumference, was really 36 1/4”. Its analog readout showed measurements...
