Solution

Given:
Highest Value (H) =48
Lowest Value (L) =22

Range = Highest Value − Lowest Value

i.e R= H− L

Substituting the given values in the formula.

R= 48 − 22 = 26

$Coefficient of Range = \frac{H - L}{H + L} = \frac{48 - 22}{48 + 22} = \frac{26}{70} = 0.37$
Thus, range is 26 and coefficient of range is 0.37
