Free Statistics Division Webinar: Acceptance Sampling Using Z1.4 – April 25, 2017 at 12:00PM EST

Join the Statistics Division on Tuesday, April 25th at 12:00PM Eastern for a webinar to be given by Dan O’Leary.

Acceptance sampling is a common method to determine if the output of a process, the product, should move to the next process or ship to the customer. One common sampling technique is attribute sampling using ANSI/ASQ Z1.4:2003. This presentation explains how to use the standard to determine sampling plans (single, double, and multiple) using an incoming inspection example. The quality engineer needs to understand the binomial distribution, the basis for these sampling plans. This leads to characterizing the risk, described by the operating characteristic (OC) curve. Understanding the OC curve helps determine some distinguished points related to the acceptable and rejectable quality levels (AQL & RQL) and the associated producer’s and consumer’s risk. The standard can help screen rejected lots; the average outgoing quality (AOQ) and average outgoing quality limit (AOQL) describe the plan’s performance.

Free Statistics Division Webinar: Empirical Root Cause Analysis – March 29, 2017 at 2:00PM Eastern Time

Join the Statistics Division on Wednesday, March 29rd at 2:00PM Eastern for a webinar to be given by Matthew Barsalou

This webinar will describe how to conduct an empirical root cause analysis. A brief mention of reasons for performing a root cause analysis will be given followed by typical tools. A case will be made for using empirical root cause analysis. The correct application of the scientific method will also be explained. This includes concepts such as Exploratory Data Analysis for hypothesis generation as well as the attributes of a good hypothesis. John Platt’s version of the scientific method will be explained using examples and these concepts will be combined into a Plan-Do-Check-Act process.

The concept of empirical root cause analysis will be depict in the form of a graphic which will show the various steps to combine Exploratory Data Analysis, the scientific method, and Box’s iterative inductive deductive process into a Plan-Do-Check-Act like method. Examples will be presented to illustrate these concepts. Real world examples will include the analysis of a cracked cable coating, vibration sensor failures and a bushing and bracket failure. This final section of the presentation will provide advice on how both the customer and supplier can better prepare for a complaint. The view of both customers and suppliers will be represented including information the customer must provide with a claim as well as how a supplier can better prepare for a customer issue.

Free Statistics Division Webinar Presented in Spanish: Análisis de Capacidad del Proceso (Ppk) en la Ausencia de Normalidad – December 20, 2016 at 9:00 AM Pacific Time

Join the Statistics Division on Tuesday, December 20th at 9:00 – 10:00 AM PST for a webinar to be given by Eduardo Santiago, Technical Training Specialist at Minitab.

El análisis de capacidad de un proceso requiere de la evaluación de la variación y la comparación del desempeño del proceso con respecto a sus especificaciones. Tradicionalmente decimos que un proceso es capaz si la mayoría de las partes que produce se encuentran dentro de especificación, en otras palabras si la tasa de defectos es pequeña. Inicialmente este análisis fue popularizado por Joseph Juran en su Manual de Control de Calidad, y hoy en día la capacidad de un proceso se mide por lo regular en función de su Cpk y Ppk.

A pesar de la simplicidad en el cálculo de dichos estadísticos, la falta de entendimiento de estos métricos de capacidad pueden conducirnos a su malinterpretación o peor aún la manipulación de tales sin haber antes mejorado el proceso. Por lo tanto es importante entender los supuestos necesarios para validar e interpretar los estadísticos de capacidad. En esta presentación, discutiremos cómo validar los supuestos, pero más importante, cómo lidiar con situaciones cuando los supuestos han sido violados.

En este seminario consideraremos tres enfoques para tratar datos que no están normalmente distribuidos:

1) Hablaremos de las transformaciones de Box-Cox y Johnson

2) Discutiremos la utilización de distribuciones no-normales, y por último,

3) Utilizaremos métodos alternos para estimar con mayor exactitud y precisión los estadísticos de capacidad.

The ASQ Statistics Division is proud to announce that the Lloyd Nelson award was presented at this year’s Fall Technical Conference. The award recognizes the paper in the ASQ journal, Journal of Quality Technology (JQT), which has “the greatest immediate impact to practitioners”.

As the editor of ASQ’s Industrial Quality Control, Nelson in the 1960s proposed dividing the magazine into two publications. Eventually, he convinced the board to create the general-interest magazine Quality Progress and the more technical quarterly Journal of Quality Technology. He became the first editor of the Journal of Quality Technology. Nelson was honored in 2001 as one of the first recipients of ASQ’s Distinguished Service Medal. He was named an ASQ Fellow in 1964 and was awarded the Shewhart Medal in 1978. Nelson also served on ASQ’s Awards Board and Shewhart and Deming Medal Committees, and was a long-time member of the Journal of Quality Technology’s Editorial Review Board.

This year, the Lloyd Nelson Award was presented to Russell V. Lenth for his outstanding paper “The Case Against Normal Plots of Effects”, published in Volume 47, Issue 2. Russ attended the Fall Technical Conference in October in Minneapolis to receive the plaque.

The abstract for the award winning paper reads as follows:

When analyzing effects in an unreplicated experiment, normal or half-normal plots of the effects (also called Daniel plots) are a popular way to visualize them and to judge which are active. This article discusses the ways in which these plots can be confusing and misleading. There are other methods available that are less subjective, easier to explain, more powerful, and less likely to be misinterpreted. I recommend against using Daniel plots, even as a supplement to one of these better analyses.

This paper has been given Open Access by the publisher until October 2017 and can be found at the following link:
