What formula is used to measure Total Process Variation(?t) in terms of Gage(?m) and Part(?p) Variation?
OPTIONS
- a) (ơm + ơp)/2
- Squareroot of (ơm squared+ ơp squared)
- (ơm + ơp)
- ((ơm + ơp) * 2)1/2
ANSWER
Squareroot of (ơm squared+ ơp squared)
EXPLANATION
ơm = Gage Variation ơp = Part Variation ơt (Total Process Variation) = √(ơm2+ ơp2)
