Find the median

Hi,

I have a few questions to complete.
HEre is one of them...

If D  =  [20,9,100,38,16,31,73,97,42,39,99,90,74,22,95,48,94,20,89,26]

What is the median of the data in D?

Your answers must be numerical (e.g. 1.5, (5+3)/2, etc.)

Help with the answer and how I go about working these sorts of questions out would be amazing.

Re: Find the median

What I would do is firstly arrange the set of numbers in ascending order. Then, cross out the first and last number, then the second and second last number, then the third and third last number, then the fourth and fourth last number, and so forth until you reach the middle number(s) of your number set.
If there is one number in the middle, it is the median.
If there are two numbers in the middle, the average of the two is the median.
