Question

41. If median = 12. Q, = 6, Q, = 22 then the coefficient of quartile deviation is
(a) 33.33
(b) 60
(c) 66.67
(d) 70​

Answer 1

GIVEN :

If median=12, ,  then the co-efficient of quartile deviation is​

TO FIND :

The value of  the co-efficient of quartile deviation

SOLUTION :

Given that the values are median=12, ,  

The formula for the co-efficient of quartile deviation  is given by

Now, substituting the values in the formula we get,

=0.57

∴ the value of the Co-efficient of quartile deviation =0.57
