How do you find the median of a column in SQL?
Median (M)= [ 6/2 ] = 3rd value of the dataset + [ 6/2 + 1 ]= 4th value of the dataset. = (4+6)/2 = 5. So, the median value in this case is 5. Usually, it is difficult to calculate the median value of a specified dataset by using Transact SQL because there is no built-in function available for this purpose.
