Answer» Explanation: Here, Highest value (H)= 35 Lowest value (L) = 15 RANGE= Highest value − Lowest value i.e. R= H− L Substituting the given VALUES in the formula R= 35 − 15= 20 Coefficient of Range is as follows: CR = H-L H+L or, CR = 35-15 35+15 = 20 50 ⇒ CR =0.4 Hence, the range (R) of the above data is 20 and coefficient of Range (CR) is 0.4

Answer»

Explanation:

Here,

Highest value (H)= 35

Lowest value (L) = 15

RANGE= Highest value − Lowest value

i.e. R= H− L

Substituting the given VALUES in the formula

R= 35 − 15= 20

Coefficient of Range is as follows:

CR =

H-L

H+L

or, CR =

35-15

35+15

⇒ CR =0.4

Hence, the range (R) of the above data is 20 and coefficient of Range (CR) is 0.4
