求助：G R&R
!(http://www3.6sq.net/cdb/pic/C2wi_GR&R.jpg)
求助：
用户反馈信息：I run the Gage R&R based on the data in your attached file, and got difference result. The %study is higher(over 30%), which means the measurement system is not good at process control. The %tolerence is over 20% a little bit, probably OK, but still need to improve. The most variation is due to repeatability is high, you need to find out the root casue. You can see detailed report in attached.
疑问： %Study Var＝33.15与%Contribution＝10.99 的数值代表什么意思？哪个重要？平常 G R&R指地是哪个值？
谢谢！

代表的是针对您所取样的数据所计算总变差，例如：由于量具重复性与再现性原因而导致该数据变差占由于该取样数据总变量的百分比。
%Study Var 研究变差百分比
在没有指定过程容差的情况下：我认为它就是量具的R＆R，当然它也就是我们最终需要的值。
当指定过程容差的情况下：那么MINITAB会产生%tolerence 项，当然我们主要参考的是该值了。
