Given a table represents the class 8 attendance
We need to find the median of the data set, so we will arrange the data in order from the least to the greatest as follows:
20 , 21 , 24 , 25 , 25
The number of data = 5
So, the median will be the data number = (5+1)/2 = 6/2 = 3
so, the median of the dat = 24
