Here's your shmoop du jour, brought to you by the San Francisco Giants.

00:08

Beating them is a...tall order.

00:12

What is the strong correlation between weight and a player's salary?

00:29

And here are the potential answers...

00:33

This problem is asking us to figure out if there's some kind of correlation...

00:36

or relationship...between player weight and salary.

00:40

If there is... we have our fingers crossed for Prince Fielder.

00:44

Anyway, it's instantly clear that we can use graph 2 to get our answer.

00:49

To figure out the relationship, we can look at the pattern the red dots make...

00:52

...or the lack of pattern?

00:57

They seem as all-over-the-place as Mr. Fielder's dietary habits.

01:01

It looks kind of like a negative relationship at first...

01:04

...increases...

01:07

...but then again everything sort of hovers equally around the middle.

01:11

Again... just like with Prince Fielder.

01:14

So...this lack of correlation means there is no strong correlation between a player's

01:19

weight and a player's salary.

01:21

Answer D is our answer!

01:24

Huge sigh of relief.

01:25

Keep packing away those M&M's, Prince.
