One entry per answer. This is in the vein of the Stack Overflow question What’s your favorite “programmer” cartoon?.

P.S. Do not hotlink the cartoon without the site's permission please.

I do have to ask though- how come cartoons are in and jokes are out? –  Sharpie Jul 22 '10 at 5:09

These cartoons are useful too; they can be included in a lecture on a particular topic where you are trying to explain a concept (e.g. correlation/causation above). A little humor can help to keep an audience engaged. –  Shane Jul 22 '10 at 14:22

yeah but.... this one isn't true... it mostly depends on how you parameterize the time variable $t$... i guess if you go back far enough, but come on... –  Jason Sep 22 '11 at 17:24

"The bridge of life"

I took this image from here. This is a "Painting commissioned by Karl Pearson", see. It is considered as a predecessor of the hazard function.

The 'Death' attempts to kill you at different ages using different sorts of weapons which are related to the "failure probability" at the corresponding age.

It would help dense people like me to see some brief explanation of how this is specifically related to data analysis. Also, please acknowledge (or at least link to) the source: give credit where credit is due. –  whuber May 11 '12 at 19:48

@whuber Thanks for your comment. I added a bit of details in order to clarify its meaning and relationship with statistics. –  user10525 May 11 '12 at 23:15

This is not a cartoon, but a joke worth mentioning:

A statistic professor travels to a conference by plane. When he passes the security check, they discover a bomb in his carry-on-baggage. Of course, he is hauled off immediately for interrogation.

"I don't understand it!" the interrogating officer exclaims. "You're an accomplished professional, a caring family man, a pillar of your parish - and now you want to destroy that all by blowing up an airplane!"

"Sorry", the professor interrupts him. "I had never intended to blow up the plane."

"So, for what reason else did you try to bring a bomb on board?!"

"Let me explain. Statistics shows that the probability of a bomb being on an airplane is 1/1000. That's quite high if you think about it - so high that I wouldn't have any peace of mind on a flight."

"And what does this have to do with you bringing a bomb on board of a plane?"

"You see, since the probability of one bomb being on my plane is 1/1000, the chance that there are two bombs is 1/1000000. This way I am much safer..."

Independence!!! –  KH Kim May 12 '12 at 10:28

But if you know that "there is a bomb" (yours) in the plane, which we may call event $A$, and you are willing to accept that the "existence of a second bomb" (event $B$) is independent of $A$, then $P(B\mid A)=P(B)=1/1000$. Always condition on what you know. And yeah, I deserve a $-1$ for screwing a good joke. –  Zen Aug 28 '12 at 18:52

@Zen again, why do you explain this? Even the security check guy in the story understand this, intuitivelly... don't analyze a joke :-) –  Curious Sep 29 '12 at 21:46

By the way, as far as I know, the person who first described this anecdote was none other than Hugo Steinhaus (of the Steinhaus-Banach theorem fame) in his "Mathematical Kaleidoscope". –  January Nov 9 '12 at 12:50

Another one from xkcd:

enter image description here

Hover Text:

Knuth Paper-Stack Notation: Write down the number on pages. Stack them. If the stack is too tall to fit in the room, write down the number of pages it would take to write down the number. THAT number won't fit in the room? Repeat. When a stack fits, write the number of iterations on a card. Pin it to the stack.

Explaining Away

Since these are a rather sampling theoretic set of cartoons so far, here's one for the Bayesians. (Actually I set it as a class question last year.)

A Frequentists vs. Bayesians cartoon from XKCD!

http://xkcd.com/1132/

Mouse-hover transcript:

'Detector! What would the Bayesian statistician say if I asked whether the--' [roll] 'I AM A NEUTRINO DETECTOR, NOT A LABYRINTH GUARD. SERIOUSLY, DID YOUR BRAIN FALL OUT?' [roll] '... Yes.'

I am not sure about this one ... the Frequentist Reasoning seems wrong to me but I cannot explain why :(. –  steffen Nov 9 '12 at 13:50

I'm biased towards the Bayesian interpretation, but the frequentist appears to me to be consistent with the standard frequentist interpretation. I hate null hypothesis significance testing, but if you want to go that route, it seems the null hypothesis is that the sun did not explode. If the null hypothesis is true, the chances of observing a "Yes" would indeed be $\frac{1}{36}$ (negligibly higher if you want to be pedantic and include the chance of a machine malfunction). So we've either seen a rare event and the sun is still there or the sun is gone. Many frequentists default to the latter. –  Michael McGowan Nov 9 '12 at 14:42

Of course, using a threshold of $p < 0.05$ is ridiculous in this case, but unfortunately many frequentists don't think about other thresholds. –  Michael McGowan Nov 9 '12 at 14:42

@steffen I would contend that using "$H_0$ = Sun did explode" is not really appropriate in this case. The null hypothesis is supposed to be the default position, so unless I have an incredibly strong reason to believe otherwise, my default will be that the sun did not explode. –  Michael McGowan Nov 9 '12 at 15:56

No one put up a cartoon from the cartoon guide to statistics. I like many of them from there and I used a number of them in one of my books. The one that seems to get the most laughs when I use it in a lecture is the one with the statistician going out on a first date. Their comments and thoughts about the making decisions on the menu with the statistician assessing probabilities and the woman just choosing what she likes makes it really hilarious.

Yes. Thanks a lot Bill. I didn't have any idea how I could paste it in. Is uppose I could have scanned it in to a file and then tried pasting it. That would have been a lot of trouble. Is that what you did? There are a few more scenes in that one that are also pretty funny. But this gets the idea across. –  Michael Chernick May 7 '12 at 21:06

I think it's that for any other type of presentation, you'd have started by telling a joke. But since mathematicians (or statisticians, here) only think and speak in terms of formulas, this was their (still lame) joke-analogue for opening a presentation. –  AdamO Dec 17 '11 at 22:15

More of a math cartoon than a data analysis cartoon, but also one that makes you think a bit.
