Statistical Process Control: the Founders' Way: SPC Book - Statistical Method from the Viewpoint of Quality Control by Walter A. Shewhart
http://statistical-process-control.blogspot.com/2007/10/statistical-method-from-viewpoint-of.html
Statistical Process Control: the Founders' Way. Sunday, October 21, 2007. SPC Book - Statistical Method from the Viewpoint of Quality Control by Walter A. Shewhart. Nearly all of the books about Statistical Process Control. Are quite awful. They contain errors, poor examples, and promote bad practices. Except for a few that may still exist, there is only one book one can recommend for sure: it's "Statistical Method from the Viewpoint of Quality Control". By Walter A. Shewhart. 1938 , Dr Shewhart illumina...

Statistical Process Control: the Founders' Way: Common and Special Causes
http://statistical-process-control.blogspot.com/2007/10/common-and-special-causes.html
Statistical Process Control: the Founders' Way. Wednesday, October 31, 2007. Common and Special Causes. From 1703 until his death in 1705, Jacob Bernoulli exchanged a number of letters with Gottfried Leibniz. Leibniz wrote to him:. Nature has established patterns originating in the return of events but only for the most part. Therefore, can't we argue that a new experience could deviate from the law of all the previous ones, even a little bit, because of the very essence of variability of things? S artic...

Statistical Process Control: the Founders' Way: Quality Gamebox
http://statistical-process-control.blogspot.com/2007/10/quality-gamebox.html
Statistical Process Control: the Founders' Way. Wednesday, October 31, 2007. Quality Gamebox 2.0. Is a collection of simulations and experiments that is both entertaining and educational. Each game demonstrates and explains classic concepts that are useful in quality management and SPC. Quality Gamebox uses colorful graphics, animation, and sound to enhance the learning experience.

Statistical Process Control: the Founders' Way: SPC Control Limits (LCL and UCL)
http://statistical-process-control.blogspot.com/2007/11/control-limits.html
Statistical Process Control: the Founders' Way. Thursday, November 15, 2007. SPC Control Limits (LCL and UCL). Define the predictable process variations. In practice it cannot be known without some associated probability. Nevertheless, Control Limits. From the founder Shewhart. S point of view, should not be confused with Confidence Interval. Notably, it is a mistake to use Student t-distribution. To estimate SPC Control Limits. The basics of Statistical Process Control. Posted by Lean Management.

Probability Concepts for Statistical Process Control: Central Limit Theorem
http://probability-concepts.blogspot.com/2007/11/central-limit-theorem.html
Probability Concepts for Statistical Process Control. Saturday, November 3, 2007. The Central Limit Theorem. States that if a sum of independent. And identically-distributed random variables has a finite variance, then it will be approximately normally distributed. And the sampling distribution will have the same mean as the population, but the variance divided by the sample size. In short the Central Limit Theorem. As the number of variables grows.

Probability Concepts for Statistical Process Control: Independency in Probability
http://probability-concepts.blogspot.com/2007/11/independency-in-probability.html
Probability Concepts for Statistical Process Control. Monday, November 5, 2007. The odds against there being a bomb on a plane are a million to one, and against two bombs a million times a million to one. Next time you fly, cut the odds and take a bomb. 8212; Benny Hill. Two events are independent if the occurrence of one of the events gives us no information about whether or not the other event will occur; that is, the events have no influence on each other.

http://probability-concepts.blogspot.com/2007_11_01_archive.html
Probability Concepts for Statistical Process Control. Thursday, November 15, 2007. A confidence interval (CI) is an interval estimate of a population parameter. Instead of estimating the parameter by a single value, an interval of likely estimates is given. Posted by Lean Management. Thursday, November 15, 2007. Monday, November 5, 2007. 8212; Benny Hill.
