This question gives you a list of numbers and asks you to find the median.
00:04
The list that it gives is 0 .2, 1 .4, 0 .6, 0 .2 again, 2 .5, 1 .9, 0 .8, and 1 .5.
00:19
Now, clearly this is not in order.
00:22
And to find a median, we need to have some sort of ordered list that is going from lowest to highest or highest to lowest.
00:28
So if we're going to find our median by hand, we need to put this in order somehow.
00:33
So the way i'm going to do that is lowest to highest, and i'll sort this.
00:37
It's going to be 0 .2, 0 .2, 0 .6, 0 .8.
00:44
We'll have 1 .4, 1 .5, 1 .9, and then finally, 2 .5.

Now, when we have an ordered list like this, if we have an ordered list of length n, we know that the median is at point n plus 1 over 2...
