This is a more than type frequency distribution table. To find the median of this data, draw the graph of this data.
Now, total number of observations in this data, N = 40.
N/2 = 20.
In order to find the median, locate 20 on y-axis. From this point, draw a line parallel to the x-axis cutting the curve at a point. From this point, draw a perpendicular to the x-axis. The point of intersection of this perpendicular with the x-axis determines the median of the data. The median is some what approximately to 34.

The given data can be converted into a normal class interval frequency distribution as follows:
Class interval
Frequency
0 - 12
40 - 37 = 3
12 - 24
37 - 30 = 7
24 - 36
30 - 18 = 12
36 - 48
18 - 13 = 5
48 - 60
13 - 4 = 9
60 - 72
