NAKED STATISTICS

STRIPPING THE DREAD FROM THE DATA

How to analyze “the numbers behind the news [and appreciate] the extraordinary (and growing) power of data” in today’s market-driven economy.

Wheelan (Public Policy/Dartmouth Coll.; 10½ Things No Commencement Speaker Has Ever Said, 2012 etc.) extends the scope of his 2002 best-seller, Naked Economics, to encompass the statistical know-how necessary in making informed economic and other decisions. The author provides tools to help the nonmathematical reader develop an intuitive grasp of apparently arcane topics such as the “central limit theorem,” which is used to estimate likely outcomes. Using forensic medicine as an analogy, he compares a statistician to a detective gathering information at the scene of a crime. Both are frequently involved in “building a circumstantial case based on imperfect data” and are dependent on sampling techniques. Wheelan uses a seemingly high-risk marketing campaign by Schlitz beer to illustrate the point. In 1981, the company spent $1.7 million to run a blind taste test between Schlitz and Michelob, involving 100 contestants. In fact, as Wheelan shows, it was a sure winner. While the likely outcome of a random sample would be a 50/50 split, any percentage could be framed to Schlitz's advantage. The key was in the sample. Contestants were selected on the basis of their previously expressed preference for Michelob, so that even if only 30 percent chose Schlitz, the claim that Michelob drinkers chose Schlitz was still valid. The author explains how the normal distribution works and emphasizes the importance of measuring both the mean and medium in a given study. Wheelan also explains the famous brain-teasing Monty Hall problem, which has stumped experts for years.

A delightful, informative guide to an often-intimidating subject.

THE ELEMENTS OF STYLE

50TH ANNIVERSARY EDITION

Privately published by Strunk of Cornell in 1918 and revised by his student E. B. White in 1959, that "little book" is back again with more White updatings.

Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis (whoops — "A bankrupt expression") a unique guide (which means "without like or equal").

DEAR MR. HENSHAW

Possibly inspired by the letters Cleary has received as a children's author, this begins with second-grader Leigh Botts' misspelled fan letter to Mr. Henshaw, whose fictitious book itself derives from the old take-off title Forty Ways W. Amuse a Dog. Soon Leigh is in sixth grade and bombarding his still-favorite author with a list of questions to be answered and returned by "next Friday," the day his author report is due. Leigh is disgruntled when Mr. Henshaw's answer comes late, and accompanied by a set of questions for Leigh to answer. He threatens not to, but as "Mom keeps nagging me about your dumb old questions" he finally gets the job done—and through his answers Mr. Henshaw and readers learn that Leigh considers himself "the mediumest boy in school," that his parents have split up, and that he dreams of his truck-driver dad driving him to school "hauling a forty-foot reefer, which would make his outfit add up to eighteen wheels altogether. . . . I guess I wouldn't seem so medium then." Soon Mr. Henshaw recommends keeping a diary (at least partly to get Leigh off his own back) and so the real letters to Mr. Henshaw taper off, with "pretend," unmailed letters (the diary) taking over. . . until Leigh can write "I don't have to pretend to write to Mr. Henshaw anymore. I have learned to say what I think on a piece of paper." Meanwhile Mr. Henshaw offers writing tips, and Leigh, struggling with a story for a school contest, concludes "I think you're right. Maybe I am not ready to write a story." Instead he writes a "true story" about a truck haul with his father in Leigh's real past, and this wins praise from "a real live author" Leigh meets through the school program. Mr. Henshaw has also advised that "a character in a story should solve a problem or change in some way," a standard juvenile-fiction dictum which Cleary herself applies modestly by having Leigh solve his disappearing lunch problem with a burglar-alarmed lunch box—and, more seriously, come to recognize and accept that his father can't be counted on. All of this, in Leigh's simple words, is capably and unobtrusively structured as well as valid and realistic. From the writing tips to the divorced-kid blues, however, it tends to substitute prevailing wisdom for the little jolts of recognition that made the Ramona books so rewarding.
