If, for example, you measure a particle, the device or system you use might provide slightly different answers every time you measure the same particle.ANOVA Gauge RR seeks to remove this variation so different recordings of the same object or target give the same answer.Use this object as the basis for defining your ANOVA Gage RR study.Your studys theory will concern the natural variation in a particular measurement system and how ANOVA Gage RR corrects it.
Your aim here is to capture as many variations in the measurements as possible. ![]() Make sure each part is labeled so you can study variations in each object. The larger the survey you can conduct, the more accurate results you can render. If you had 20 people each measuring one object then rotate the objects between your testers and repeat the tests. Once each tester has tested each object once, rotate the testing machine or device between each of the testers and repeat. In the end each object will have been tested by each tester on each testing device. Already you will be able to gauge the variations in the measurements. From the evidence you might be able to determine the root cause of certain variations. For example, if one object is consistently bigger than the others it may be a manufacturing malfunction, if one tester routinely makes errors in measurement it may be their lack of skill and if it is one machine or measuring device making the errors you can identify that as the cause. However, chances are that the variations will be inconsistent. Choose the program you think best suits your object, objectives and measurement system. It will provide you with a more accurate result for your measurements. ![]() References Six Sigma: R R Repeatability and Reproducibility Minitab: Fundamentals of Gage RR Resources Minitab: Fundamentals of Gage RR Writer Bio Mark Wollacott began writing professionally in 2009.
