% study variation in gage r&r

WebGage repeatability & Reproducibility (Gage R&R) is define as the method to discover how much of the process variation is due to the measurement equipment and measurement method. This method is design to evaluate the effects of repeatability & reproducibility separately, and as a combine overall error of measurement. WebFrom this analysis, the % Gage R&R is 7.76%. The AIAG reference manual does include ANOVA as a way of analyzing a Gage R&R study. In fact, using these same data, the manual now says that the test method is acceptable since the % Gage R&R is below 10. What? How can it be one thing with the Average and Range method and another with the ANOVA?
