To find the median of ungrouped data:
for example find the median of 1,2,6,4,5,3,6.
1. First arrange the data in the increasing order 
   1,2,3,4,5,6,6
2. median is the ( \frac{n+1}{2} )^{th} element in the data.
   here n=number of elements = 7
   (n+1)/2 = 4th element is 4.
  So median is 4.
3. in case when n is even, 
   for example, find the median of 1,3,7,10
   (n+1)/2 = 5/2 = 2.5
   now the median is the average of 2 and 3 rd element.
   median = (3+7)/2 = 5
