Consider the following frequency distribution:

Class 0-5 6-11 12-17 18-23 24-29
Frequency 13 10 15 8 11

The upper limit of the median class is
(A) 17              (B) 17.5                       (C) 18              (D) 18.5

Frequency distribution: It tells how frequencies are distributed over values in a frequency distribution. However mostly we use frequency distribution to summarize categorical variables.
Class in not continuous. So we have to make 1t continuous first.

Class Frequency Cumulative Frequency
0-5.5 13 13
5.5-11.5 10 (13+10=23)
11.5-17.5 15 (23+15=38)
17.5-23.5 8 (38+8=46)
23.5-29.5 11 (46+11=57)
  N = 57  

\frac{N}{2}= \frac{57}{2}= 28\cdot 5
Here the median class is 15.5 – 17.5
upper limit of median class is 17.5
