This question gives you a list of data and asks you to find the median.
00:04
The data that it gives is 28 .4, 9 .1, 3 .4, 27 .6, 59 .8, 32 .1, 47 .6, and 29 .8.
00:31
Now before we can find a median, we need to put this in order.
00:35
That is rearrange this so it's going from lowest to highest or highest to lowest.
00:41
I'm going to do lowest to highest.
00:42
Doing that, we'll get 3 .4, 9 .1, next is 27 .6, then 28 .4, then 29 .8.
00:57
And we'll get 32 .1, 47 .6, and finally the last 59 .8.
01:05
So now it's an order.
01:07
And when we have an ordered list of length n, we know that the median is at entry n plus 1 over 2.
01:15
That is, n plus 1 over 2 will give us a number, and then we count that number into the list, and we'll find our median...
