how do you work out the median of a list of numbers when there are two numbers that are in the middle.
You add them together and divide by 2.
For example, $\displaystyle 1,2,3,4,5,6,7,8$
take
$\displaystyle 4+5=9 $
=$\displaystyle \frac{9}{2} $
=$\displaystyle 4.5 $
Is this what you were speaking of?
Also, if there are two numbers in the middle that are the same. Ex. 1,2,2,3 the median simply becomes that middle number, in this case 2.
