That is certainly, a book about the ways by which bad statistics are produced and spread through world. The title with the book originates from Mark Twain’s famous expression “lies, damned lies, and statistics, which is usually interpreted as grouping statistics with lies. An even more critical title would range from phrase “figures don’t lay, but liars can figure.
Despite their cynical title, Best’s publication is one of the best ways to learn how to cease being awestruck by statistics, and to begin critically assessing them.
In uncomplicated prose stuffed with real world cases, Joel Ideal deconstructs processes by which social statistics are set up and take on a life of their own, primarily through blind and unquestioning repetition by the press. He as well delineates just how such statistics are sometimes mutated, misinterpreted, misapplied, and manipulated.
In his look at, there are no perfect figures, just better or worse ones. Every single statistic involves human choices: defining what to measure, identifying how to assess it, choosing whom to count or perhaps how to depend it, and choosing how to approach unreported cases (the darker figure) of whatever is being counted. Not only does every figure contain identifiable, though generally unrecognized strong points, weaknesses, and dark characters, but many of the most controversial and heavily published statistics are set up by persons in advocacy positions.
Interpersonal statistics ” statistics regarding social problems, such as prostitution or committing suicide ” tend to be produced by activists who concern the problem, and may even exaggerate this. When not made by activists, figures are often a product of government, which may be motivated in the opposite path of the activists, to play down a problem. An easy summary from the issues and topics in this book offers a good summary of clear considering on statistical issues. Part 1, “The Importance of Interpersonal Statistics, points out where figures come from, the way you use them, and why they can be important.
Section 2, “Soft Facts, talks about sources of bad statistics. Speculating, poor explanations, poor procedures, and bad samples will be the primary types of bad statistics. Good statistics require good data; obvious, reasonable definitions; clear, fair measures; and appropriate examples. Chapter 3, “Mutant Statistics, describes the techniques for mangling numbers. Many of these arise by violating the four requirements of good statistics, but a new problem arises here. Whilst it is relatively simple to spot bad statistics, mutant statistics demand a second standard of understanding.
Since statistics mutate, they take on the history, and it becomes essential to unravel the to understand precisely how and why they are mutant. Transformation, confusion, and compound errors generate chains of bad figures that turn into difficult to search for and categorize. Chapter some, “Apples and Oranges, discusses the dangers of inappropriate comparability. Dangers arise when side by side comparisons over time require changing and unchanging measures, and projections. Comparisons among places and groups result in problems not only in the info measured, in the ways the data may be collected and collated.
Comparison amongst social challenges also produces unique issues. Best gives logic of comparison to help the reader learn how to make sense great comparison and bad assessment. Chapter a few, “Stat Wars, describes the difficulties that happen when advocated use questionable numbers to generate a case. Section 6, “Thinking About Social Statistics, amounts up Best’s advice on understanding stats ” don’t be awestruck when confronted with numbers, , nor be negative about them, this individual suggests, always be critical and thoughtful.
