The Applying Statistics to Tolerance Stacks class is a half day class.  It is usually taught together with the Tolerance Stacks Class. 

The textbook for this class was written by Dave Slopsema at Dimensional Consulting.

Students for this class are expected to already have a fundamental understanding of Geometric Dimensioning and Tolerancing.


Participants in this class receive a copy of "The Stacks Wizard."  In addition to creating stacks, the Stacks Wizard performs statistical analysis as taught in this class.  The Stacks wizard is normally sold for $25 per copy, but it is provided at no extra cost to everyone who takes the Applying Statistics to Tolerance Stacks Class.
