Hello Team, Just a query would like to clear..... I am working on a GB project where I have collected some data (Discrete/Attrbute). Currently I am in Measure Phase, where I need to measure the sigma value of the data. The data which I have collected is "Defectives", I need to compute Z value or sigma value. I have used sigma calculator which was shared during GB training from benchmark. Below mentioned are the details used in sigma calculator : 1) Defective Count - 92 2) Sample Size - 197 3) Yield - 53.30% 4) Z. Bench Sigma Value (LT) - 0.08 5) Z. Bench Sigma Value (ST) - 1.58 I also tried using Capability Analysis using Binomial Distribution of Defectives by using same data in Minitab 16. I have taken 197 as a constant subgroup size But Process Z value has shown 2.1228. (See attached file) I am stucked which z value to be followed. Please advice.. Regards, Rajiv N Mumbai
