![]() The number of levels for each factor is a function of the number of samples and the number of appraisers.Factor A is used to designate the parts or samples.A standard 2-factor ANOVA format is used for analyzing measurement systems.It is best to use a computer with DOE software for the calculations. Calculations using ANOVA are more complex than those with other techniques.ANOVA techniques are the preferred method for analyzing measurements for destructive testing.ANOVAs allow us to get an accurate estimate of variances.With an ANOVA, we can vary the number of samples, appraisers, trials, and even the number of measurement devices to get a more accurate picture of the variation in the measurement system.ANOVAs provide information on interactions between samples and appraisers.The use of ANOVA does have some advantages over standard GR&R studies: Interaction between the samples and the appraisers. ![]() Repeatability of the measurement equipment.Reproducibility between operators or appraisers.With measurement systems, we can explore how the test equipment and appraiser variables affect the measurement system output.ĪNOVAs allow us to study four measurement system components:. ![]()
