    You add them together and divide by 2.

    For example, 1,2,3,4,5,6,7,8

    take

     4+5=9

    =  \frac{9}{2}

    =  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.
