Question

Find the range and the coefficient of range for the observation 6, 11, -3, 0, 8.

Answer 1

Observations x: 6, 11, -3, 0, 8
Here, x_H = 11; x_L = – 3

Range:
Range R = x_H – x_L
= 11 – (-3) = 11 + 3 = 14

Coefficient of range:
Coefficient of range = \(\frac{R}{x_H+x_L}\)
= \(\frac{14}{11−3}=\frac{14}{8}\) = 1.75
