To find the median of a set of values with an even number of values, place the values in ascending or descending order, find the 2 middle numbers and add them together and divâ¦ide that total by 2 and that's the median.
To find the median: 1  Order the data from smallest to largest. 2  Consider whether n, the number of observations, is even or odd. 3  If n is odd, the median M is the center observation in the ordered list.  If n is even, the median M is the mean of the two center observations in the ordered list.
