(2) “Looking Out for No. 1–Math Theory Suggests Looking for 1s Can Help Detect Cooked Books” by John Allen Paulos
Source: abcnews.com – 1 March 2002
Was there any way of looking at Enron’s books and–not knowing anything about the company’s specific accounting practices–determining whether the books had been cooked? There may have been, and the mathematical principle involved is easily stated, but counterintuitive.
Benford’s Law states that in a wide variety of circumstances numbers as diverse as the drainage areas of rivers, physical properties of chemicals, populations of small towns, figures in a newspaper or magazine, and the half-lives of radioactive atoms begin disproportionately with the digit “1.”
Specifically, they begin with “1” about 30 percent of the time, with “2” about 18 percent of the time, with “3” about 12.5 percent of the time, and with larger digits progressively less often. Less than 5 percent of the numbers in these circumstances begin with the digit “9.”
(This is in stark contrast to many other situations–say where a computer picks a number between 0 and 100 at random–where each of the digits from “1” to “9” has an equal chance of appearing as the first digit.)…
A mathematically inclined accountant, Mark Nigrini, generated considerable buzz when he noted that Benford’s Law could be used to catch fraud in income tax returns and other accounting documents.
The following example suggests why collections of numbers governed by Benford’s Law arise so frequently:
Imagine that you deposit $1,000 in a bank at 10 percent compound interest per year. Next year you’ll have $1,100, the year after that $1,210, then $1,331, and so on. The first digit of your bank account remains a “1” for a long time.
When your account grows to more than $2,000, the first digit will remain a “2” for a shorter period as your interest increases. And when your deposit finally grows to more than $9,000, the 10 percent growth will result in more than $10,000 in your account the following year and a long return to “1” as the first digit.
If you record the amount in your account each year for a large number of years, these numbers will thus obey Benford’s Law.
The law is also “scale-invariant” in that the dimensions of the numbers don’t matter. If you expressed your $1,000 in euros or francs or drachmas and watched it grow at 10 percent per year, about 30 percent of the yearly values would begin with a “1,” about 18 percent with a “2,” and so on.
More generally, Hill showed that such collections of numbers arise whenever we have what he calls a “distribution of distributions,” a random collection of random samples of data. Big, motley collections of numbers follow Benford’s Law.
And this brings us back to Enron, accounting, and Nigrini, who reasoned that the numbers on accounting forms, which come from a variety of company operations, each from a variety of sources, fit the bill and should be governed by Benford’s Law.
That is, these numbers should begin disproportionately with the digit “1,” and progressively less often with bigger digits, and if they don’t, that is a sign that the books have been cooked. When people fake plausible-seeming numbers, they generally use more “5s” and “6s” as initial digits, for example, than would be predicted by Benford’s Law.
Nigrini’s work has been well-publicized and has no doubt been noted by accountants and by prosecutors. Whether the Enron and Arthur Andersen people have heard of it is unclear, but investigators might want to check if the percentage of leading digits in the Enron documents is what Benford’s Law predicts. Such checks are not fool-proof and sometimes lead to false positive results, but they provide an extra tool that might be useful in certain situations.
It would be amusing if, in looking out for No. 1, the culprits forgot to look out for their “1s.” Imagine the Andersen shredders muttering that there weren’t enough leading “1s” on the Enron documents they were feeding into the machines. A 1-derful fantasy!

The authors conducted an exhaustive empirical study with the aid of custom software, public search engines and powerful statistical techniques, in order to determine the relative popularity of every integer between 0 and one million. The resulting information exhibits an extraordinary variety of patterns which reflect and refract our culture, our minds, and our bodies.
For example, certain numbers, such as 212, 486, 911, 1040, 1492, 1776, 68040, or 90210, occur more frequently than their neighbors because they are used to denominate the phone numbers, tax forms, computer chips, famous dates, or television programs that figure prominently in our culture. Regular periodicities in the data, located at multiples and powers of ten, mirror our cognitive preference for round numbers in our biologically-driven base-10 numbering system. Certain numbers, such as 12345 or 8888, appear to be more popular simply because they are easier to remember.
Humanity’s fascination with numbers is ancient and complex. Our present relationship with numbers reveals both a highly developed tool and a highly developed user, working together to measure, create, and predict both ourselves and the world around us. But like every symbiotic couple, the tool we would like to believe is separate from us (and thus objective) is actually an intricate reflection of our thoughts, interests, and capabilities. One intriguing result of this symbiosis is that the numeric system we use to describe patterns, is actually used in a patterned fashion to describe.
We surmise that our dataset is a numeric snaphot of the collective consciousness. Herein we return our analyses to the public in the form of an interactive visualization, whose aim is to provoke awareness of one’s own numeric manifestations.

(4) “Students May Be Learning More About Avoidance Strategies Than Arithmetic In Math Class; Study Shows What Teachers Can Do”
Article’s lead author: Julianne C. Turner: (574) 631-3429; firstname.lastname@example.org
“Please don’t call on me” can be a pervasive thought by students who are not doing well in math class. By early adolescence, it is common for some students to become experts in avoidance strategies — avoiding asking for help when they need it, withdrawing effort and resisting novel approaches to learning — in order to deflect attention from low ability. This type of behavior can cause students to fall further behind academically and may eventually lead some to drop out of school. But new research shows that teachers that emphasize learning rather than performance may help prevent this self-destructive behavior. The findings appear in the current issue of the Journal of Educational Psychology, published by the American Psychological Association (APA).
In their study involving 1,092 sixth-grade students in 65 sixth-grade classrooms in four ethnically and economically diverse school districts in three Midwestern states, Julianne C. Turner, Ph.D. of the University of Notre Dame and co-authors surveyed the students to determine use of avoidance strategies. The study also included the use of trained observers who watched and audiotaped nine of the students’ teachers while they taught their math classes.
The researchers found that students reported using fewer avoidance techniques in classrooms perceived as emphasizing learning, understanding, effort and enjoyment. In those classrooms, teachers helped students who had problems understanding, gave them opportunities to demonstrate new competencies and provided substantial motivational support for learning. Teachers in these “mastery-oriented” classrooms made sure their students did not feel inadequate or ashamed when they did not understand. “By modeling their own thinking processes, these teachers demonstrated that being unsure, learning from mistakes, and asking questions were natural and necessary parts of learning,” according to the authors. By contrast, “students reported higher incidences of avoidance strategies in classrooms in which teachers devoted little attention to helping students build understanding and in which motivational support was low.”
The teacher observations, say the authors, provided valuable insight into how teaching methods affect avoidance behaviors. For instance, in a classroom where students used more avoidance strategies, the teacher placed greater emphasis on getting an answer correct, with little discussion about the important concepts in a lesson and little explanation of why an answer was correct. If a student did not know the answer, the teacher would ask another student and did not usually stop to explain the answer. “Because the teacher typically did not respond to mistakes and misunderstandings with explanations or allow students to explain their strategies, his students may have felt vulnerable to public displays of incompetence and adopted more avoidance strategies,” explained the researchers.
In classrooms where students used fewer avoidance strategies, the teachers tended to model, hint and elicit support from other students to help their students learn. In those classrooms, the students were active participants in instructional discourse that stressed understanding and explanation. “Perhaps because they knew their teachers and peers would help, students in these classrooms did not seem to need to adopt avoidance strategies to appear able to others,” said the authors.
Classrooms with students who reported using avoidance strategies less also had teachers that used math-related humor as part of their lessons. Humor may lessen tension and encourage students to view their math classes as more enjoyable, say the authors.
