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

Step-by-step explanation:

Solution :

L - 125 and S = 63

Range = L - S

= 125 - 63

Range = L - S = 62

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

L + S = 125 + 63 = 188

Coefficient of range = 62/188

= 31/94

= 0.33

(ii) 43.5, 13.6, 18.9, 38.4, 61.4, 29.8

L - 61.4 and S = 13.6

Range = L - S

= 61.4 - 13.6

Range = L - S = 47.8

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

L + S = 61.4 + 13.6 = 75

Coefficient of range = 47.8/75

= 478/750

= 0.64
