Simulation of Within and Between Variation for Specification Setting
Created: May 21, 2019 08:32 AM

Suppose you characterized the variation in the weight of tablets from a new process and then wanted to use that work to estimate the variation in weight that could be expected in a multi-tablet package.

 

One way to get the multi-tablet estimate is to simulate a large number of tablets with a specified mean and sigma, using a normal distribution. Then divide the individual tablets into a large number of subgroups, sum the weights and then look at the variation in the subgroupScreen Shot 2019-05-21 at 8.28.12 AM.pngScreen Shot 2019-05-21 at 8.28.12 AM.png
