At least one of these graphs implies that if the US wanted to reduce the number of drivers getting hit by trains, they simply just need to stop importing oil from Norway.
What variables are you correlating in that example? It seems to correlate just fine if your measuring energy inputed to heat the room vs work done by air conditioner.
There are no humans with three or more arms. Most humans have two arms. A few humans have one or zero arms. Thus, the mean/average number of arms should be between 1.9 and 2.0 but surely less then two.
first, I am aware of the stats so the lecture was a waste.
second, the posters name was sharkweek, if you went in the water during sharkweek you probably wouldn't have two arms, this is what is known as a joke based on an eponysterical name.

There are some cases where lack of correlation is actually evidence of causation.
As in the causal effect happens to cancel out a confounder, or something more fun? Do you have an example?
I was thinking of an air conditioner - a perfect A/C would mean the temperature is flat. Although hmm, I think R^2 is undefined rather than 0 there.
But basically, it's a "if you do it right, it'll look like you've done nothing at all" situation.

Hah! I love this kind of stuff
REPORT: Average human has less than two arms
The average human has approximately one testicle and one boob.
You could also say that the most humans have an above-average number of arms
well, sure, after sharkweek!

(The median number of arms is two though)

third, you are also incorrect in your statement that there are no humans with 3 arms https://www.google.com/search?q=baby+born+with+three+arms
You are right. I was wrong. You win this debate.
There are no humans with three or more arms
Never say never:

Prove it.
Average human has more than 1 skeleton!
(pregnancy)
Some people own skeletons.
The extra ones are usually kept in the closet, I believe.
All own at least one. Some, two.
