Question

Find the coefficient of range for the following data.
1, 4, 5, 5, 2, 7

• A. 0.25
• B. 0.5
• C. 0.8
• D. 0.75

Answer 1

The correct option is D 0.75

1, 4, 5, 5, 2, 7

Largest Value L = 7
Smallest Value S = 1

$Coefficientofrange=\frac{L-S}{L+S}$
= $\frac{7-1}{7+1}$
= $\frac{6}{8}$
= $0.75$
