Another mistaken notion connected with the law of large numbers is the idea that an event is more or less likely to occur because it has or has not happened recently. The idea that the odds of an event with a fixed probability increase or decrease depending on recent occurrences of the event is called the gambler's fallacy. For example, if Kerrich landed, say, 44 heads in the first 100 tosses, the coin would not develop a bias towards the tails in order to catch up! That's what is at the root of such ideas as "her luck has run out" and "He is due." That does not happen. For what it's worth, a good streak doesn't jinx you, and a bad one, unfortunately , does not mean better luck is in store.

A single death is a tragedy; a million deaths is a statistic.

A small sample, we repeat, is rarely the big scientific problem. Interpretation is.

A statistical anomaly does not prove wrongdoing. Delma Kinney, a fifty-year-old Atlanta man, won $1 million in an instant lottery in 2008 and then another $1 million in an instant game in 2011. The probability of that happening to the same person is somewhere in the range of 1 in 25 trillion.

A statistically significant finding gives you a clue, suggesting a promising place to focus your research energy. The significance test is the detective, not the judge. <...> If a result is novel and important, other scientists in other laboratories ought to test and retest the phenomenon and its variants, trying to figure out whether the result was a one-time fluke or whether it truly meets the Fisherian standard of “rarely fails.” That’s what scientists call replication; if an effect can’t be replicated, despite repeated trials, science backs apologetically away. The replication process is supposed to be science’s immune system, swarming over newly introduced objects and killing the ones that don’t belong.

A vast army of government employees [Central, state and local government] of around 20 million are taken care by the remaining 380 million of the workforce, which also meets the extortionate and rent-seeking demands of the government employees.

Coincidence”, he finally said. “Statisticans looking for connections can always find odd coincidences and statistical anomalies, if they try hard enough.

Baseball is a soap opera that lends itself to probabilistic thinking. [Dick Cramer]

Be careful of averages and how they’re applied. One way that they can fool you is if the average combines samples from disparate populations. This can lead to absurd observations such as: "On average, humans have one testicle.

Be wary, though, of the way news media use the word “significant,” because to statisticians it doesn’t mean “noteworthy.” In statistics, the word “significant” means that the results passed mathematical tests such as t-tests, chi-square tests, regression, and principal components analysis (there are hundreds). Statistical significance tests quantify how easily pure chance can explain the results. With a very large number of observations, even small differences that are trivial in magnitude can be beyond what our models of change and randomness can explain. These tests don’t know what’s noteworthy and what’s not—that’s a human judgment.

Black Swans and tail events run the socioeconomic world

By the time your perfect information has been gathered, the world has moved on.

Descriptive statistics can be like online dating profiles: technically accurate and yet pretty darn misleading.

Convincing - and confident - disciplines, say, physics, tend to use little statistical backup, while political science and economics, which have never produced anything of note, are full of elaborate statistics and statistical “evidence” (and you know that once you remove the smoke, the evidence is not evidence).

Facts are stubborn things, but statistics are pliable.

Every lateness give us a staggering statistics in negative economic effect

Fire, knives, automobiles, hair removal cream. Each of these things serves an important purpose. Each one makes our lives better. And each one can cause some serious problems when abused. Now you can add statistics to that list.

He could not believe that any of them might actually hit somebody. If one did, what a nowhere way to go: killed by accident; slain not as an individual but by sheer statistical probability, by the calculated chance of searching fire, even as he himself might be at any moment. Mathematics! Mathematics! Algebra! Geometry! When 1st and 3d Squads came diving and tumbling back over the tiny crest, Bell was content to throw himself prone, press his cheek to the earth, shut his eyes, and lie there. God, oh, God! Why am I here? Why am I here? After a moment's thought, he decided he better change it to: why are we here. That way, no agency of retribution could exact payment from him for being selfish.

Flo especially took me in hand. When I felt I had to prove the existence of discrimination with statistics, for instance, she pulled me aside. 'If you're lying in the ditch with a truck on your ankle,' she said patiently, 'you don't send someone to the library to find out how much the truck weighs. You get it off!

Her statistics were more than a study... For her, Quetelet was the hero as scientist, and the presentation copy of his Physique Sociale is annotated by her on every page. Florence Nightingale believed—and in all the actions of her life acted upon that belief—that the administrator could only be successful if he were guided by statistical knowledge. The legislator—to say nothing of the politician—too often failed for want of this knowledge.

He who says that someone isn’t himself is a victim of statistics.

How results that are not indicative of anything can be produced by pure chance—given a small enough number of cases—is something you can test for yourself at small cost. Just start tossing a penny. How often will it come up heads? Half the time of course. Everyone knows that. Well, let’s check that and see…. I have just tried ten tosses and got heads eight times, which proves that pennies come up heads eighty percent of the time.

His secret, like those of nine of his fellow seniors, is safe with me. At Milton High, I’m my own statistic. People fail to see the great equalizer, the one thing the band geeks, the drama nerds, the jocks, and the preppies all have in common. Me-Mercedes Ayres. The girl who took their virginity.

How easy it is for so many of us today to be undoubtedly full of information yet fully deprived of accurate information.

If the universe was scientific and just left to itself, then we’d have statistical probabilities to rely on. But once people are involved it sometimes becomes much more problematic because they’re erratic. People do crazy things that don’t make sense.

I don't believe in the glory and the dream. I believe in statistics.

If proof were needed that statistics alone are not enough in establishing value, then VT Trumper is that proof.

If the statistics are boring, then you've got the wrong numbers.

If college admissions officers are going to encourage kids to take the same AP math class, why not statistics? Almost every career (whether in business, nonprofits, academics, law, or medicine benefits from proficiency in statistics. Being an informed, responsible citizen requires a sound knowledge of statistics, as politicians, reporters, and bloggers all rely on "data" to justify positions. [p.98]

If I want to understand an individual human being, I must lay aside all scientific knowledge of the average man and discard all theories in order to adopt a completely new and unprejudiced attitude. I can only approach the task of understanding with a free and open mind, whereas knowledge of man, or insight into human character, presupposes all sorts of knowledge about mankind in general.

If your experiment needs a statistician, you need a better experiment.

I guess I think of lotteries as a tax on the mathematically challenged.

If you want what’s best for your kids, one surefire way to provide them with a healthy, happy home is to make sure they have lesbian parents. In the longest-running study of lesbian families to date,2 zero percent of children reported physical or sexual abuse—not a one. In the general population, 26 percent of children report physical abuse and 8.3 percent report sexual abuse.

I have studied many languages-French, Spanish and a little Italian, but no one told me that Statistics was a foreign language.

I have stressed this distinction because it is an important one. It defines the fundamental difference between probability and statistics: the former concerns predictions based on fixed probabilities; the latter concerns the inference of those probabilities based on observed data.

I just wish that Statistics was as easy as arranging numbers in chronological order, finding the median, lower and upper quartiles, and placing them on a Box and whisker's chart

In Alabama, even though 65 percent of all homicide victims were black, nearly 80 percent of the people on death row were there for crimes against victims who were white.

In 2012, an estimated 14,827 persons were murdered in the United States. -- Federal Bureau of Investigation

In my opinion, defining intelligence is much like defining beauty, and I don’t mean that it’s in the eye of the beholder. To illustrate, let’s say that you are the only beholder, and your word is final. Would you be able to choose the 1000 most beautiful women in the country? And if that sounds impossible, consider this: Say you’re now looking at your picks. Could you compare them to each other and say which one is more beautiful? For example, who is more beautiful— Katie Holmes or Angelina Jolie? How about Angelina Jolie or Catherine Zeta-Jones? I think intelligence is like this. So many factors are involved that attempts to measure it are useless. Not that IQ tests are useless. Far from it. Good tests work: They measure a variety of mental abilities, and the best tests do it well. But they don’t measure intelligence itself.

In a world with amazing amounts of statistics and demographics available, If you don't utilize foresight, statistics, demographics, projections and predictions the competition will.

Information or allegations reflecting negatively on individuals or groups seen less sympathetically by the intelligentsia pass rapidly into the public domain with little scrutiny and much publicity. Two of the biggest proven hoaxes of our time have involved allegations of white men gang-raping a black woman-- first the Tawana Brawley hoax of 1987 and later the false rape charges against three Duke University students in 2006. In both cases, editorial indignation rang out across the land, without a speck of evidence to substantiate either of these charges. Moreover, the denunciations were not limited to the particular men accused, but were often extended to society at large, of whom these men were deemed to be symptoms or 'the tip of the iceberg.' In both cases, the charges fit a pre-existing vision, and that apparently made mundane facts unnecessary. Another widely publicized hoax-- one to which the President of the United States added his sub-hoax-- was a 1996 story appearing in USA Today under the headline, 'Arson at Black Churches Echoes Bigotry of the Past.' There was, according to USA Today, 'an epidemic of church burning,' targeting black churches. Like the gang-rape hoaxes, this story spread rapidly through the media. The Chicago Tribune referred to 'an epidemic of criminal and cowardly arson' leaving black churches in ruins. As with the gang-rape hoaxes, comments on the church fire stories went beyond those who were supposed to have set these fires to blame forces at work in society at large. Jesse Jackson was quoted was quoted in the New York Times as calling these arsons part of a 'cultural conspiracy' against blacks, which 'reflected the heightened racial tensions in the south that have been exacerbated by the assault on affirmative action and the populist oratory of Republican politicians like Pat Buchanan.' Time magazine writer Jack White likewise blamed 'the coded phrases' of Republican leaders for 'encouraging the arsonists.' Columnist Barbara Reynolds of USA Today said that the fires were 'an attempt to murder the spirit of black America.' New York Times columnist Bob Herbert said, "The fuel for these fires can be traced to a carefully crafted environment of bigotry and hatred that was developed over the last century.' As with the gang-rape hoaxes, the charges publicized were taken as reflecting on the whole society, not just those supposedly involved in what was widely presumed to be arson, rather than fires that break out for a variety of other reasons. Washington Post columnist Dorothy Gilliam said that society in effect was 'giving these arsonists permission to commit these horrible crimes.' The climax of these comments came when President Bill Clinton, in his weekly radio address, said that these church burnings recalled similar burnings of black churches in Arkansas when he was a boy. There were more that 2,000 media stories done on the subject after the President's address. This story began to unravel when factual research showed that (1) no black churches were burned in Arkansas when Bill Clinton was growing up, (2) there had been no increase in fires at black churches, but an actual decrease over the previous 15 years, (3) the incidence of fires at white churches was similar to the incidence of fires at black churches, and (4) where there was arson, one-third of the suspects were black. However, retractions of the original story-- where there were retractions at all-- typically were given far less prominence than the original banner headlines and heated editorial comments.

Out of every one hundred Americans, fewer than two get aid from today’s cash welfare program. Just 27 percent of poor families with children participate. There are more avid postage stamp collectors in the United States than welfare recipients.

In the days when the white engineers were disputing the attributes of the feeder system that was to be, one of them came to Enzian of Bleicherode and said, "We cannot agree on the chamber pressure. Our calculations show that a working pressure of 40 atü would be the most desirable. But all the data we know of are grouped around a value of only some 10 atü." "Then clearly," replied the Nguarorerue, "you must listen to the data." "But that would not be the most perfect or efficient value," protested the German. "Proud man," said the Nguarorerue. "What are these data, if not direct revelation? Where have they come from, if not from the Rocket which is to be? How do you presume to compare a number you have only derived on paper with a number that is the Rocket's own? Avoid pride, and design to some compromise value." – from Tales of the Schwarzkommando, collected by Steve Edelman

In the business people with expertise, experience and evidence will make more profitable decisions than people with instinct, intuition and imagination.

Love doesn't read statistics!

Maar wie het zeker weet, is per definitie niet nieuwsgierig. Wie koste wat het kost vasthoudt aan zijn overtuigingen, staat nooit open voor nieuwe informatie. Willen we goed met cijfers – en informatie in het algemeen – omgaan, dan zullen we die onzekerheid moeten omarmen.

Many a statistic is false on its face. It gets by only because the magic of numbers brings about a suspension of common sense.

More data means more information, but it also means more false information.

Nature has established patterns originating in the return of events, but only for the most part. New illnesses flood the human race, so that no matter how many experiments you have done on corpses, you have not thereby immposd a limit on the nature of events so that in the future they could not vary.

Numbers never lie, after all: they simply tell different stories depending on the math of the tellers.
