Frequency 6 9 11 14 23 10

Solution

Items Frequency
(f)
Cumulative Frequency
(c.f.)
3
4
5
6
7
8
6
9
11
14
23
10
6
15
26
40
63
73
N = 73

Median = size of N+12thitem
or, Median = size of 73+12thitem
or, Median = size of 742th item = size of 37th item.
Now, we need to locate this item in the column of Cumulative Frequency. The item just exceeding 37th is 40 (in the c.f. column), which is corresponding to 6. ​ Hence, median is 6.
