The Web of Statistics

Youden Address

by Lenth, Russell

How statisticians and practitioners approach statistics (and even the very nature of data) has changed considerably over the years, and it will continue to evolve as the nature and type of data change. Moreover, these shifts have required statistical results to be communicated differently. Technology and the Internet are important aspects of all of this. In this article, ``web'' refers more broadly to all of the connections between what we do, how we think about it, the tools we use, and who we serve. The more we understand this web, the better we can do our jobs and prepare for changes in the future. These considerations touch on quality practices (fitness for purpose, per Juran), and statistical engineering (assembling and organizing our tools to suit the purpose).

ASA’s Committee on Professional Ethics: A brief note

by Hogan, Howard

The American Statistical Association (ASA) Committee on Professional Ethics is involved in education and outreach pertaining to ethical issues in statistical practice. The Committee provides a set of Ethical Guidelines regarding professionalism and a statistician’s responsibilities. This article also describes the history of ASA’s ethics guidelines for statisticians.

Accelerating Product and Process Development Through Parallel Thinking and Experimentation

Mini-paper October 2012 Newsletter

by Kevin Gallagher; Dave Sartori;

Mikel Harry, one of the founding fathers of the Six Sigma movement, once stated that the next evolution in Six Sigma will not be towards higher levels of process capability but instead will involve a breakthrough in the quality of thought at the individual level. In this paper application of this philosophy is used to accelerate new product and process development with a methodology driven by question generation and parallel-thinking. There are typically many, many questions that need to be answered to close the gap in our understanding of Y = f(x) for a given product or process, consider ways in which you can answer these questions in parallel to accelerate your knowledge capture. By definition, multifactor DOEs already accomplish this. But often there are questions about the variation in the measurement system or underlying process or both. In this paper, a case study has been provided in which questions about the effects of controllable factors where answered in parallel with questions rega

Use of the Socratic Method in Teaching Statistical Thinking

by Jensen, Willis A.

Use of the Socratic Method in Teaching Statistical Thinking Description: There are many opportunities for teaching statistical concepts whether they occur in formal or informal settings. Many different teaching approaches can be used to best take advantage of these opportunities. In order to develop statistical thinking skills a Socratic teaching approach can be helpful. An example of applying a Socratic approach is given here as well as a discussion of how to successfully apply it in teaching situations.

Probability of Detection Analysis for Eddy Current Inspection Systems

Fall 2011 Mini-Paper

by Brown, Jennifer;

Eddy Current (EC) inspection is a Nondestructive Testing (NDT) method commonly used for flight quality assurance of commercial, military, and rocket engine hardware. One application of EC inspection is to detect surface or near-surface anomalies before they grow to a critical length which could impact the structural integrity of the hardware. EC inspection uses the principal of electromagnetism or the production of a magnetic field by current flowing in a conductor. Anything placed in the magnetic field that has electric and/or magnetic properties will change the field and produce an EC signal. Understanding the relationship between crack size and system response is the basis for determining the detection capability of an EC system. For a given EC system, the relationship between the EC response and crack size can be evaluated by scanning a set of standard specimens with a known number and distribution of crack sizes. The results are analyzed using the "a-hat versus a" analysis method to
