I just took up a little studies on GRR method and got confused with all the terms and their representations, such as EV, %EV, AV, %AV, GRR, %GRR, PV, %PV, TV, and P/T Ratio.
Let's say I have this values:
EV = 0.20188 %EV = 17.62%
AV = 0.22963 %AV= 20.04%
GRR = 0.30575 %GRR = 26.88%
PV = 1.10456 %PV = 96.38%
TV = 1.14610
NOTE: These values are taken from MSA 3rd Ed(Pg 114),based upon 6 Std. Dev., and the K1,K2,K3 values are inverse of the d2 table.
So, is there any meaning to each of the value, and what they represent?
Another question is, for calculating AV, we use a K2 constant, derived fomr the d2 Table with g = 1. My question is, why is g = 1? What is one range calculation?
Thanks a lot.
