Comparison of the classical variation coefficient with calculated with the ring method for survey BOST results
Journal Title: Production Engineering Archives - Year 2016, Vol 0, Issue 2
Abstract
This article presents two methods of the variation coefficient calculating: the classical method and the ring method. These methods were used to study the distribution of pairs of validity ratings on the map of stability for two factors: the stability of the process and the quality of the product. Coefficients of variation for each zone are dependent on the method of their calculation.
