The GAGE Application

Getting Started

Suppose that ABC Company needs to evaluate a gasket thickness gage. Three operators (George, Jane, and Robert) are selected for this study. Using the same gage, each operator measures ten parts (gaskets) in a random order. Each part is measured by each operator twice (two trials). Table A.1 gives the measurements (gasket thicknesses) collected by each operator and is patterned after an example given in Measurement Systems Analysis Reference Manual (1990).

Table A.1: Gage Study Data

	George		Jane		Robert
Part	Trial1	Trial2	Trial1	Trial2	Trial1	Trial2
1	0.65	0.60	0.55	0.55	0.50	0.55
2	1.00	1.00	1.05	0.95	1.05	1.00
3	0.85	0.80	0.80	0.75	0.80	0.80
4	0.85	0.95	0.80	0.75	0.80	0.80
5	0.55	0.45	0.40	0.40	0.45	0.50
6	1.00	1.00	1.00	1.05	1.00	1.05
7	0.95	0.95	0.95	0.90	0.95	0.95
8	0.85	0.80	0.75	0.70	0.80	0.80
9	1.00	1.00	1.00	0.95	1.05	1.05
10	0.60	0.70	0.55	0.50	0.85	0.80

These data are used to illustrate the GAGE application throughout this appendix.
