Question

Find the range and coefficient of range of the following data

63, 89, 98, 125, 79, 108, 117, 68

Answer 1

Here the largest value (L) = 125

The smallest value (S) = 63

Range = L – S = 125 – 63 = 62

Coefficient of range = `("L" - "S")/("L" + "S")`

= `(125 - 63)/(125 + 63)`

= `62/188`

= 0.33
