摘要:

This article traces the development of the design of experiments from origins in the mind and professional experience of R.A. Fisher between 1922 and 1926. The article indicates how the analysis of variance procedure stimulated design, being justified by the principle of randomization that Fisher introduced with the analysis, and exploited by his use of blocking and replication. The article indicates the radically new form and efficiency of factorial block designs, shows the further advantages accruing to factorial arrangements through confounding, and suggests how Fisher's close collaboration with experimenters stimulated these developments.

摘要:

The following four papers on the teaching of statistics were presented at a session sponsored by Mu Sigma Rho and the Section on Statistical Education at the annual ASA meeting in San Diego in 1978. The four authors are well qualified to discuss the subject of teaching statistics, and the papers present much helpful material for use by teachers of statistics. Since the four papers contain many personal views and opinions, the Editorial Board felt that it would be most appropriate to publish the papers essentially as they were presented at the San Diego meeting.

摘要:

It is argued that a nonparametric framework for the introductory statistics course is both mathematically and conceptually simpler than the customary normal-theory framework. Two examples are considered: the Kendall rank correlation coefficient versus the Pearson product-moment correlation coefficient, and the confidence interval for the median versus the confidence interval based on the one-sampletstatistic.

摘要:

We often forget how science and engineering function. Ideas come from previous exploration more often than from lightning strokes. Important questions can demand the most careful planning for confirmatory analysis. Broad general inquiries are also important. Finding the question is often more important than finding the answer. Exploratory data analysis is an attitude, a flexibility, and a reliance on display, NOT a bundle of techniques, and should be so taught. Confirmatory data analysis, by contrast, is easier to teach and easier to computerize. We need to teach both; to think about science and engineering more broadly; to be prepared to randomize and avoid multiplicity.

摘要:

This two-quarter sequence in research methods and statistics for nurses, taught by a statistician, avoids some of the common problems of service courses in statistics and provides training opportunities in statistical consultation for graduate students in statistics. The student-evaluation methods measure the reasoning process inherent in both research methods and statistics. Formative evaluations of the sequence indicate that it is successful in maintaining interest among students and increasing confidence in their ability to critique research articles, including statistical aspects of these. The teaching and evaluation methods can be used for other groups of students from the same discipline.

摘要:

Ten guidelines in the form of “commandments” are offered to scientists and statisticians who testify before government bodies such as congressional committees, regulatory agencies, or judicial panels. These guidelines are illustrated by examples of testimony by the author and others. Efforts to communicate highly technical material to nontechnical audiences are often frustrated by communication breakdowns. These difficulties can be avoided by making simple statements in plain English, but this isn't so easy as it sounds. The commandments suggest that preparation and hard work are needed to avoid the mistakes that are commonly made in testimony.

摘要:

This article is a write-up of an invited talk given at a national meeting of the American Statistical Association. It discusses the problem of getting people to use statistics properly and emphasizes the importance of using good logic in drawing inferences from statistics. The job of a good statistical consultant is to sponsor the use of correct logic in his or her client's activities. Statisticians in general should be interested in finding more and better ways of introducing good logic at early levels of the education process.

摘要:

The question of why a geometric or coordinate-free approach to linear models has been subordinated to an algebraic approach is considered by reviewing selected papers having a geometric slant. These begin with R.A. Fisher's 1915 paper on the distribution of the correlation coefficient and continue through William Kruskal's elegant 1975 paper on the geometry of generalized inverses. The thesis is put forward that the relative unpopularity of the geometric approach is not due to an inherent inferiority but rather to a combination of inertia, poor exposition, and a resistance to abstraction.
