Question

Consider the data

The frequency of the upper limit of the median class and the lower limit of the modal class is

Answer 1

Correct Answer - C

Here, `(N)/(2)=(67)/(2)=33.5` which lies in the interval 125-145.
Hence, upper limit of median class is 145. Here, we see that the highest frequency is 20 which lies in 125-145. Hence the limit of modal class is 125.
Required difference=Upper limit of median class-Lower limit of modal class =145-125=20
