# Consider the following frequency distribution:

The upper limit of the median class is

A. 16.5

B. 18.5

C. 18

D. 17.5

Answer :

To find median class,

Assume Σf_{i} = N = Sum of frequencies,

f_{i} = frequency of class intervals

and C_{f} = cumulative frequency

Lets convert this data into exclusive type of data.

So, N = 57

⇒ N/2 = 57/2 = 28.5

The cumulative frequency just greater than (N/2 = ) 28.5 is 38, so the corresponding median class is 11.5 - 17.5.

∴ Upper limit of this median class = 17.5
