Question
Find the range and coefficient of range of the following data
43.5, 13.6, 18.9, 38.4, 61.4, 29.8
Solution
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
