Question

Calculate quartile ans its coefficients from the following data weges lessthan 35, 35-37, 38-40, 41-43, over43. Frequency 14, 62, 99, 18, 7

Answer 1

Answer:

ANSWER:

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
