Investopedia explains 'Median'
To find the median value in a list with an odd amount of numbers, one would find the number that is in the middle with an equal amount of numbers on either side of the median. To find the median, first arrange the numbers in order from lowest to highest:
List: 3, 13, 2, 34, 11, 26, 47
Arranged in order, the list becomes: 2, 3, 11, 13, 26, 34, 47
The median is the number in the middle: 2, 3, 11, 13, 26, 34, 47
13 is the median in the list of numbers since there are 3 numbers on either side.
