I am confused on what is the estimated median . Some say the median is n/2 while others say n+1/2. Which one should i use? suppose the cumulative frequency is up till 40, the textbook says that the median value is 20 but why cant it be 20.5?
the median: n/2 or n+1/2 Watch

n is an even number:
Median = (4+1)/2 th number = 2.5th number = 5.5
n is an odd number:
Median = (5+1)/2 th number = 3rd number = 8Last edited by Math12345; 01-06-2016 at 20:25.
