From the following data, calculate range and coefficient of range.

Range = L-S

Here, L = Largest value, S = Smallest value

L = 70, S = 10

Range = 70-10 = 60

Coefficient of Range =L-S/+L+S = 70-10/70+10 = 60/80 = 0.75

Here, L = Largest value, S = Smallest value

L = 70, S = 10

Range = 70-10 = 60

Coefficient of Range =L-S/+L+S = 70-10/70+10 = 60/80 = 0.75
