Journal of the American Statistical Association, June 1984 newer users can evaluate the usefulness of the technlque for the problem at hand. Chapters 3 and 4 are used to introduce BMDP program usage conventions. In Chapter 3 new users are given a sample program, annotated output, and guidelines on how data should be prepared for the analysis. Chapter 4 contains an overview of BMDP syntax rules and usage notes. Job-control language is introduced in just enough detail to enable the uninitiated to run ajob on an IBM or similar system. Features common to all BMDP programs are introduced in Chapters 5, 6, and 7. Topics presented include paragraph structure, formats, editing and transforming data, and BMDP Save Files. The section on Save Files is especially clear and makes this facility more readily accessible to persons who are not fluent in IBM's Job Control Language (JCL) and file terminology. The remaining chapters describe statistical methods implemented in the 40 programs that comprise the BMDP library. Chapters 8, 9, 10, and 12 discuss those programs treating data description. Capabilities described in these chapters include simple data description, description and comparison of treatment levels, plots and histograms, and treatment of missing data. Chapter 11 contains an extensive description of frequency table analysis together with a variety of examples. Numerous regression modeling techniques are available. Five linear regression techniques are presented in Chapter 13. Chapter 14 covers nonlinear regression, including a derivative-free algorithm and stepwise logistic regression. Five different techniques for performing ANOVA and MANOVA are presented in Chapter 15. Chapters 16 and 17 cover nonparametric analyses and cluster analysis. Chapter 18, "Multivariate Analysis," discusses techniques such as factor analysis, canonical correlation, and stepwise discriminant analysis. Chapter 19 treats life-table and survival analyses. Chapter 20 contains descriptions and examples of programs that perform spectral and Box-Jenkins time series analyses. BMDP has long had a reputation for being computationally rigorous. Annotated computing formulas for all multivariate methods, tests, and measures used in frequency table analysis and random number generation are given in Appendix A. Appendixes B, C, D, and E treat special topics, such as methods to increase the size of programs, the JCL needed to run BMDP on an IBM system, and a list of selected articles from BMDP Communications. The 1981 edition of the BMDP user's guide represents a substantial improvement over previous editions. The type and layout are easier to read and are similar to that found in JASA. The editors have reached a compromise between a manual that tries to be a complete course in data analysis and one that assumes that users are concerned only with statement syntax. BMDP's reference manual is one of the few that provides examples that consider both simple and difficult data analyses. Each chapter's presentation illustrates virtually all of the available program options. The presentation is appropriate for technically sophisticated scientific users who need concise information about how to use this powerful research tool.

The Art of Asking Questions. Stanley L. Payne. Princeton, NJ: Princeton University Press, 1980. xvi + 249 pp. $5.95 (paperback).

Stanley Payne's classic treatise on survey question wording has been reissued in paperback. In a new foreword George Gallup, Sr., observes, "I have found none of Stanley Payne's trenchant observations to be any less appropriate today than they were almost thirty years ago, when the book was written" (p. vii). The reviewers agree with Gallup's assessment. This lively, sensible, and readable book will continue to provide useful guidance to professional survey planners for at least another 30 years, and probably for as long as human beings are involved in asking and answering survey questions. Although written in a lighthearted and humorous tone, The Art of Asking Questions is a serious attempt to catalog general rules for formulating individual survey questions. In doing so, Payne incorporates insights into the use of words and language, the nature of respondents, the importance of familiarity with the survey topic, and the mechanics of questionnaire construction itself. He emphasizes the need to match the frames of reference of the respondent and the questionnaire designer, to use words that are unambiguous and convey the intended meaning of a question, and to formulate the content and structure of response categories to capture accurately the respondent's reply. Payne's central thesis, stated at the outset (p. 16), is that problems in question construction can generally be traced to hidden and unwarranted assumptions; the purpose of the book is to provide the researcher with effective strategies for critically evaluating survey questions to reveal those assumptions and to eliminate their potential biasing effects. Yet as the title says, this is an "art" book and not a "science" book. For example, Payne gives a very complete exposition of the advantages and disadvantages of the use of open-ended questions without precisely prescribing when they are preferable to multiple choice questions and when they should be avoided. In the final analysis, judgments about the effectiveness and necessity of their use are left to the researcher. To take another example, Payne presents an enumeration of various ways of "loading" a question, which he defines as wording a question to lead some respondents to give different answers than they would give to another wording of what was intended to be the same issue (p. 77). His examples cover a wide range of ways in which unintended distortions in response might be introduced, and his prescriptions in this area ought to be considered by any conscientious questionnaire designer. One large question remains, though: If two wordings produce different results, which one is less loaded? The answer may not always be clear. A. BUBOLZ Although Payne's main focus is on the stimulus presented by single THOMAS Iowa State University questions, he occasionally addresses broader topics. His insights into the use of questionnaires to elicit public opinion (e.g., the crystallization of attitudes), the distinction between having an opinion and intensity of opinion, and the possible need to ask more than one question to obtain a meaningful answer (e.g., the discussion of Gallup's "quintamensional Geigy Scientific Tables, Vol. 2. design") are valid today and are now receiving some attention in the social science community (Turner and Martin 1984).
