This is how you find the median in a set of numbers:
1. Arrange the numbers from smallest to largest value.
2. Next you find the number that is in the very middle, that is the median.
3. If there are two numbers that are in the middle you add them together and then divide by two.
In the example, for instance, 19,050 an 19,600 are the two middle numbers. So you add them together (19,050 + 19,600 = 38,650) and then divide by two to get your median (38,650/2 = 19,325).
So 19,325 is your median.
Hope this helps! :)
