The Median is considered to be the "middle number" in a variety of set numbers. To find it, you would need to arrange all the numbers from least to greatest, then find the middle number.
Let's say we have: 27, 23, 24, 16, 19, 30, 34.
Arrange these from smallest to greatest: 16, 19, 23, 24, 27, 30, 34.
To find the middle number, cross off one number from the left and right. Repeat this process until you have one number left.
In the off chance that you have TWO numbers remaining, what you would need to do is add both numbers and divide by 2.
