Formula: Median (Ungrouped Data)
If n is odd:
Median =\[\left(\frac{n+1}{2}\right)\]th observation
If n is even:
Median average of =\[\frac{n}{2}\mathrm{th}\] and \[\left(\frac{n}{2}+1\right)\mathrm{th}\]observations

Formula: Median (Grouped Data)
\[\mathrm{Median}=l+\frac{\left(\frac{n}{2}-cf\right)}{f}\times h\]
-
l = lower limit of median class
-
n = total frequency
-
cf = cumulative frequency of class before median class
-
f = frequency of median class
Classes must be continuous before applying the median formula.
