The number that separates the first and second half of a data set or population is called as the median. It can be used to determine an approximate average. In other words, it is the mid value or the average value of the given data set. The median formula is given for even data set and odd data set. If number of data is even , then median is the sum of the middle two value divide by 2. If number of data is odd, then the middle number of the data set is median.
To find median, first arrange the elements in ascending order and then find the middle number. The above median formula will help you to calculate median for both odd and even values. Also, you can navigate to the online calculator provided above to calculate median.
