How to Find the Median of a Set of Numbers
The median is the exact middle of numbers in a sequence or set.
Steps
You must use the formula (x+1)/2 to find the place at which you must record your value. ex. 2, 4, 6, 8, 9. (5+1)/2
3 The value at the third position is 6 therefore the median is 6.
If you have an odd set of numbers
- Sort your set of numbers from least to greatest.
- Find the number that is in the middle. The median for 5, 3, 1, 7, 2 would be 3. An easy way to approach this is to put one finger on 1 and the other on 7. Then count down from there.

If you have an even set of numbers
- Sort out your set of numbers from least to greatest.
- Find the average of the two numbers in the middle. 2 and 3 are both in the middle, so you need to add 2 and 3, then divide the sum by 2. The formula for finding the average of two numbers is (the sum of the two middle numbers)/2.
