Anova Gage R&r Template
Describes and rates three methods to analyze a Gage R&R study: Average and Range method, ANOVA, and EMP (Evaluating the Measurement Process). The ANOVA Gage R&R statistical method estimates the amount of variability induced in measurements by the measurement system itself. The calculations used in the X-bar and R method are simpler, however the ANOVA method is more accurate. In a Gage R&R study, it is important that the measurements are done in a random order and that the parts selected provide a representative sample across the possible range of responses.

A Gage Repeatability and Reproducibility (Gage R&R) study is a great way to understand the variation in a measurement process. You don’t need special software like Minitab.

If you just want to do Gage R&R in Excel quickly and reliably then save youself the headache and download my. Many people using special software just plug in the numbers without understanding what is being calculated. If you follow this article you will fully understand the math’s. But when it’s time to perform actual Gage R&R studies I strongly recomend you do use a validated tool such as Minitab or my add-in. Whats covered in this article: • • • • • • • • • • • What is Gage R&R? The variation in measurement results, or precision, is affected by many factors such as: • The operator • The equipment used • The calibration of the equipment • The environment • The time elapsed between measurements As more of these factors are varied it can be expected that the variation in measurement results will increase.
This leads to two extreme conditions of precision; repeatability and reproducibility. Repeatability is the minimum condition for precision in which the above factors are held constant while reproducibility is the maximum condition in which all of these factors vary. Often some intermediate measure of precision is relevant in which all of the possible factors effecting reproducibility are not varied since some of these will be maintained constant for the process under consideration. When designing a Gage R&R study you need to decide which reproducibility conditions will vary for the actual measurement process.
