statistics jokes

In God we trust. All others must bring data.

If had only one day left to live, I would live it in my statistics class:
it would seem so much longer.

The latest survey shows that 3 out of 4 people make up 75% of the world's population.

Three statisticians went out hunting, and came across a large deer. The first statistician fired, but missed, by a meter to the left. The second statistician fired, but also missed, by a meter to the right. The third statistician didn't fire, but shouted in triumph, "On the average we got it!"

Did you hear about the politician who promised that, if he was elected, he'd make certain that everybody would get an above average income?

There are three kinds of lies: lies, damned lies, and statistics.

Logic is a systematic method for getting the wrong conclusion with confidence.
Statistics is a systematic method for getting the wrong conclusion with 95% confidence.

A statistics major was completely hung over the day of his final exam. It was a True/False test, so he decided to flip a coin for the answers. The stats professor watched the student the entire two hours as he was flipping the coin...writing the answer...flipping the coin...writing the answer. At the end of the two hours, everyone else had left the final except for the one student. The professor walks up to his desk and interrupts the student, saying:
"Listen, I have seen that you did not study for this statistics test, you didn't even open the exam. If you are just flipping a coin for your answer, what is taking you so long?"
The student replies bitterly, as he is still flipping the coin: "Shhh! I am checking my answers!"

There was this statistics student who, when driving his car, would always accelerate hard before coming to any junction, whizz straight over it , then slow down again once he'd got over it. One day, he took a passenger, who was understandably unnerved by his driving style, and asked him why he went so fast over junctions. The statistics student replied, "Well, statistically speaking, you are far more likely to have an accident at a junction, so I just make sure that I spend less time there."

Three professors (a physicist, a chemist, and a statistician) are called in to see their dean. Just as they arrive the dean is called out of his office, leaving the three professors there. The professors see with alarm that there is a fire in the wastebasket.
The physicist says, "I know what to do! We must cool down the materials until their temperature is lower than the ignition temperature and then the fire will go out."
The chemist says, "No! No! I know what to do! We must cut off the supply of oxygen so that the fire will go out due to lack of one of the reactants."
While the physicist and chemist debate what course to take, they both are alarmed to see the statistician running around the room starting other fires. They both scream, "What are you doing?"
To which the statistician replies, "Trying to get an adequate sample size."

I asked a statistician for her phone number... and she gave me an estimate.

A statistician's wife had twins. He was delighted. He rang the minister who was also delighted.
"Bring them to church on Sunday and we'll baptize them," said the minister.
"No," replied the statistician. "Baptize one. We'll keep the other as a control.
