Summary
ANOVA in Gage R&R studies uses analysis of variance to assess measurement system variation. Students learn how to calculate and interpret the ANOVA table for these studies.
Sources of Variation
Variation in a process comes from the process itself, sampling and the measurement system. A Gage R&R study focuses on the measurement system variation, breaking it down into repeatability and reproducibility.
The ANOVA Table
The ANOVA table for Gage R&R studies includes sources of variation, degrees of freedom, sum of squares, mean squares and F values. These help to estimate the variance of each source of variation.
Sum of Squares and Degrees of Freedom
Sum of squares and degrees of freedom are key parts of the ANOVA table. They help to calculate mean squares, which estimate the variance for each source of variation. The document explains how to calculate them for different sources.
Gage R&R Results
The measurement system's contribution to total variance is calculated as a percentage. This helps to determine if the measurement system is acceptable. The document discusses how to interpret these results.
Key terms
