To find the median, arrange the numbers in acsending order.
If there is an even number of numbers add the two middles and divide by 2.
The result will be the median.
Step by Step Explaination:
Ascending order of the frequency = 7, 8, 15, 20
The number of frequency are even.
Adding the two middle nos. = 8 + 15
= 23
Divide the sum by 2 = 23/2
= 11.5
Hence, the median for the following frequency distribution table is 11.5.
