As a matter of fact, even when professional mathematicians read technical books, their eyes tend to skip over the equations. What they really want is a sympathetic friend who will explain the ideas and draw the pictures behind the equations. We will try to be that friend, for those who read our book.
Statistics is the art of making numerical conjectures about puzzling questions. What causes the resemblance between parents and children, and how strong is that force? Why does the casino make a profit at roulette? Who is going to win the next election? How many people are employed? These are difficult issues, and statistical methods help a lot if you want to think about them.
The methods were developed over several hundred years by people who were looking for answers to their questions. Some of these people will be introduced later.
With a good design, reliable conclusions can be drawn from the data. Some badly-designed studies are discussed too—so you can see the pitfalls, and learn what questions to ask when reading about a study.
Study design is perhaps our most important topic; that is why we start there. The ideas look simple, but appearances may be deceptive: part I has a lot of depth.
Descriptive statistics—the art of summarizing data—is introduced in part II. Histograms, the average, the standard deviation, and the normal curve are all considered.
The discussion continues in part III, where the focus is on analyzing relationships, for instance, the dependence of income on education. Here, correlation and regression are the main topics.
Much statistical reasoning depends on the theory of probability, discussed in part IV; the connection is through chance models, which are developed in part V.
Coins, dice, and roulette wheels are the main examples in parts IV and V. The expected value and standard error are introduced; probability histograms are developed, and convergence to the normal curve is discussed. Part VI is about estimation. For instance, how does the Gallup Poll predict the vote?
Why are some methods for drawing samples better than others?
Part VII uses chance models to analyze measurement error, and to develop genetic theory. Part VIII introduces tests of significance, to judge whether samples are consistent with hypotheses about the population.
If the model is wrong, the resulting inference may be quite shaky. Nowadays, inference is the branch of statistics most interesting to professionals. However, non-statisticians often find descriptive statistics a more useful branch, and the one that is easier to understand. That is why we take up descriptive statistics before inference.
8.Statistics (4th Ed) Freedman
The bare bones of our subject are presented in chapters 1 to 6, 13, 16 to 21, 23, and After that, the reader can browse anywhere. The next chapters to read might be 8, 10, 27, and If you work these exercises as they come along and check the answers, you will get practice in your new skills—and find out the extent to which you have mastered them.
Every chapter except 1 and 7 ends with a set of review exercises. The book does not give answers for those exercises. Such exercises must be answered without the clues provided by context. When working exercises, you might be tempted to flip backward through the pages until the relevant formula materializes.
However, reading the book backward will prove very frustrating. Review exercises demand much more than formulas. They call for rough guesses and qualitative judgments. In other words, they require a good intuitive understanding of what is going on.
The way to develop that understanding is to read the book forward. Why does the book include so many exercises that cannot be solved by plugging into a formula? The reason is that few real-life statistical problems can be solved that way. Blindly plugging into statistical formulas has caused a lot of confusion.
So this book teaches a different approach: thinking. Working drawings, however, are done freehand; the reader is encouraged to make similar sketches, rather than being intimidated by too much precision. Of the making of books, there is no end. Statistics, like people, show wear and tear from aging. Fortunately or unfortunately, data are easier to rejuvenate. We started the first edition in , and completed the fourth in These past 35 years were years of rapid change, as commentators have doubtless observed since prehistoric times.
There was explosive growth in computer use. SAT scores bottomed out around , and have since been slowly going up chapter 5. Educational levels have been steadily increasing chapter 4 , but reading skills may—or may not—be in decline chapter The population of the United States increased from million to million chapter There was corresponding growth in higher education. Over the period to , the number of colleges and universities increased from about 3, to 4, chapter The number of male faculty increased from , to ,; for women, the increase was , to , There were remarkable changes in student attitudes chapters 27, The American public gained a fraction of an inch in height, and 20 pounds in weight chapter 4.
Despite the huge increase in obesity, there were steady gains in life expectancy—about 7 years over the year period. The trend toward longer lives has major societal implications, as well as ripple effects on our exercises. Family incomes went up by a factor of four, although much of the change represents a loss of downloading power in the dollar chapter 3. Crime rates peaked somewhere around , and have fallen precipitously since chapters 2, See chapter 29; is this correlation or causation?Descriptive statistics—the art of summarizing data—is introduced in part II.
F Here, correlation and regression are the main topics.
A Model for Measurement Error 1. An Appreciation of the Model 5. Over the period to , the number of colleges and universities increased from about 3, to 4, chapter We will try to explain why the methods work, and what to watch out for when others use them. The Expected Value and Standard Error 3.
