00:03

A little birdie told us you wanted to shmoop a math problem...

00:08

A half dozen super-smart Martians took an IQ test to see how

00:12

they matched up with the average human brain.

00:15

Find the median of their IQ scores.

00:17

Here they are: 120, 206, 138, 198, 150, and 175.

00:23

And here are the potential answers...

00:29

So what's this problem asking?

00:30

Well, it's really more of a vocab question than a math problem.

00:33

The word of the day...

00:35

MEDIAN Uh... the mathematical median.

00:40

But the idea comes from the same place -- road medians divide things in the middle.

00:45

For median calculations we first put the numbers in order, low to high.

00:49

We sing the song: you know how it goes...

00:51

C'mon now sing it with me... Throw out the high.... throw out the low...

00:55

throw out the high... throw out the low....

00:58

And uh... here we stop. Works great on campfire with marshmallows.

01:02

We have two left -- 150 and 175.

01:05

To get the median, we just average the last two.

01:08

150 plus 175 is 325... divided by two and you get 162.5.

01:14

So the answer is C.

01:16

"As in, "Come in peace."
