Question

Find the range and coefficient of range of the following data

43.5, 13.6, 18.9, 38.4, 61.4, 29.8

Answer 1

The largest value (L) = 61.4

The smallest value (S) = 13.6

Range = L − S

= 61.4 − 13.6

= 47.8

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

= `(61.4 - 13.6)/(61.4 + 13.6)`

= `47.8/75`

= 0.64
