The Median of ungrouped data can be defined both for even and odd numbers. In fact, the formula differs for even and odd.
When n is odd, the Median of ungrouped data becomes-
Median = [(n+1)/2]th observation
When n is even, the Median of ungrouped data becomes
Median = mean of (n/2)th observation and [(n/2)+1]th observation, if n is even.
