Find out the range and the coefficient of range from the following data:

Daily Wage (₹) 6 7 8 9 10 11 12 15

Number of Workers 10 15 12 18 25 20 10 4

Solution

Daily Wage 6 7 8 9 10 11 12 15

No. of workers 10 15 12 18 25 20 10 4

Here,
Highest value =15
Lowest value = 6

Range (R) = Highest value (H) − Lowest value (L)
= 15 − 6
= 9

$Coefficient of Range (CR) = \frac{H - L}{H + L} = \frac{15 - 6}{15 + 6} = \frac{9}{21} = 0.429$

Hence, the Range (R) of the above series is 9 and Coefficient of Range (CR) is 0.429
