Encouraging the Next Generation of STEM Professionals

In the most recent ASQ Influential Voices post, Bill Troy, ASQ CEO, asks: how should we encourage the next generation of STEM Professionals? I addressed a similar question in: Future Engineers and Scientists, which provides many details on this question. The advantages of gaining science, technology, engineering and math skills (STEM) are fairly well known. However, even so, that is something to emphasize in order to encourage the next generation. While it is fairly well known it still helps to … Continue reading →

George Box Webcast on Statistical Design in Quality Improvement

George Box lecture on Statistical Design in Quality Improvement at the Second International Tampere Conference in Statistics, University of Tampere, Finland (1987). Early on he shows a graph showing the problems with American cars steady over a 10 years period. Then he overlays the results for Japanese cars which show a steady and significant decline of the same period. Those who didn’t get to see presentations before power point also get a chance to see old school, hand drawn, overhead … Continue reading →

Cognition: How Your Mind Can Amaze and Betray You

The webcast above is from the excellent folks at Crash Course. This webcast provides another view into the area of Deming’s management system on the theory of knowledge (the one most people forget), how we know what we know and how that belief isn’t always right. Two of the four components of Dr. Deming’s management system were about our brains (psychology is the other) which makes a great deal of sense when you think about how focused he was on … Continue reading →

George Box Articles Available for a Short Time

A collection of George Box articles have been selected for a virtual George Box issue by David M. Steinberg and made available online. George E. P. Box died in March 2013. He was a remarkably creative scientist and his celebrated professional career in statistics was always at the interface of science and statistics. George Box, J. Stuart Hunter and Cuthbert Daniel were instrumental in launching Technometrics in 1959, with Stu Hunter as the initial editor. Many of his articles were … Continue reading →

Introductory Videos on Using Design of Experiments to Improve Results

The video shows Stu Hunter discussing design of experiments in 1966. It might be a bit slow going at first but the full set of videos really does give you a quick overview of the many important aspects of design of experiments including factorial designed experiments, fractional factorial design, blocking and response surface design. It really is quite good, if you find the start too slow for you skip down to the second video and watch it. My guess is, … Continue reading →

Richard Feynman Explains the PDSA Cycle

Ok, really Richard Feynman Explains the scientific method. But his thoughts make the similarity between the PDSA cycle and the scientific method obvious. 1) Plan, hypothesis. You make a guess about a theory (in using the PDSA cycle this step is often missed, while in the scientific method this is of the highest priority). You make a prediction based on that theory. 2) Do the experiment 3) Study the results If the results disprove the theory you were wrong. If … Continue reading →

One factor at a time (OFAT) Versus Factorial Designs

Guest post by Bradley Jones Almost a hundred years ago R. A. Fisher‘s boss published an article espousing OFAT (one factor at a time). Fisher responded with an article of his own laying out his justification for factorial design. I admire the courage it took to contradict his boss in print! Fisher’s argument was mainly about efficiency – that you could learn as much about many factors as you learned about one in the same number of trials. Saving money … Continue reading →

Problems With Student Evaluations as Measures of Teacher Performance

Dr. Deming was, among other things a professor. He found the evaluation of professors by students an unimportant (and often counterproductive measure) – used in some places for awards and performance appraisal. He said for such a measure to be useful it should survey students 20 years later to see which professors made a difference to the students. Here is an interesting paper that explored some of these ideas. Does Professor Quality Matter? Evidence from Random Assignment of Students to … Continue reading →

Statistical Engineering Links Statistical Thinking, Methods and Tools

In Closing the Gap Roger W. Hoerl and Ronald D. Snee lay out a sensible case for focusing on statistical engineering. We’re not suggesting that society no longer needs research in new statistical techniques for improvement; it does. The balance needed at this time, however, is perhaps 80% for statistics as an engineering discipline and 20% for statistics as a pure science. True, though I would put the balance more like 95% engineering, 5% science. There is a good discussion … Continue reading →

Extrinsic Incentives Kill Creativity

If you read this blog, you know I believe extrinsic motivation is a poor strategy. This TED webcast Dan Pink discusses studies showing extrinsic rewards failing. This is a great webcast, definitely worth 20 minutes of your time. “you’ve got an incentive designed to sharpen thinking and accelerate creativity and it does just the opposite. It dulls thinking and blocks creativity… This has been replicated over and over and over again for nearly 40 years. These contingent motivators, if you … Continue reading →

YouTube Uses Multivariate Experiment To Improve Sign-ups 15%

Google does a great job of using statistical and engineering principles to improve. It is amazing how slow we are to adopt new ideas but because we are it provides big advantages to companies like Google that use concepts like design of experiments, experimenting quickly and often… while others don’t. Look Inside a 1,024 Recipe Multivariate Experiment A few weeks ago, we ran one of the largest multivariate experiments ever: a 1,024 recipe experiment on 100% of our US-English homepage. … Continue reading →

Does the Data Deluge Make the Scientific Method Obsolete?

The End of Theory: The Data Deluge Makes the Scientific Method Obsolete by Chris Anderson “All models are wrong, but some are useful.” So proclaimed statistician George Box 30 years ago, and he was right. But what choice did we have? Only models, from cosmological equations to theories of human behavior, seemed to be able to consistently, if imperfectly, explain the world around us. Until now. Today companies like Google, which have grown up in an era of massively abundant … Continue reading →

Fairness Matters

Sense of Fairness Affects Outlook, Decisions Burnout has been long associated with being overworked and underpaid, but psychologists Christina Maslach and Michael Leiter found that these were not the crucial factors. The single biggest difference between employees who suffered burnout and those who did not was the whether they thought that they were being treated unfairly or fairly. … Their research on fairness dovetails with work by other researchers showing that humans care a great deal about how they are … Continue reading →

Drug Price Crisis

In 2005 I posted about some of the problems with drug pricing. It is nice to find at least a couple of people at MIT that want to have MIT focus research on the public good instead of private profit. As I have mentioned too many universities now act like they are for-profit drug or research companies. That is wrong. Drug companies can do so, institutions with purported higher purposes should not be driven to place advancing science below profiting … Continue reading →

Stratification and Systemic Thinking

I am reading a fascinating book by Jessica Snyder Sachs: Good Germs, Bad Germs. From page 108: At New York Hospital, Eichenwald and infectious disease specialist Henry Shinefield conceived and developed a controversial program that entailed deliberately inoculating a newborn’s nostrils and umbilical stump with a comparatively harmless strain of staph before 80/81 could move in. Shinefield had found the protective strain – dubbed 502A – in the nostrils of a New York Hospital baby nurse. Like a benign Typhoid … Continue reading →

Toyota Engineers a New Plant: the Living Kind

Topic: Management Improvement Toyota Engineers…a Shrub Toyota Motor Corp has developed a derivative of the Cherry Sage shrub that is optimized for absorbing pollutants from the air. It seems Toyota is dominating the management improvement news in the same way Google is dominating the rest of the business news. It seems like Toyota is mentioned positively nearly as much as other companies combined on the management blogs that I read most often. And I am contributing to that. I doubt … Continue reading →
