Range - measure of dispersion , Operation Research

Assignment Help:

RANGE

Range is the difference between the highest and the lowest value is series. This is the simplest absolute measure of dispersion.

Symbolically : R= L- S

Where R= Represent Range

L= Maximum ( largest ) value and

S= Minimum (smallest ) value

Coefficient or Range

To compare the series the relative measure of dispersion is defined as:

Coefficient of Range (C. R.) = Largest Value - Smallest Value/ Largest Value + Smallest Value = L- S/ L + S
