An engineer wants to monitor the impact strength of ceramic components. The engineer randomly selects 30 components that represent the expected range of the process variation. Each component is large enough to yield 2 samples of the correct size for the test. The engineer prepares the samples from the components and assigns the same part number to samples from the same component. The operator randomly selects 10 parts for each of 3 operators to measure. The 3 operators measure the strength of each sample, two samples per part, for a total of 60 measurements.
You can use this data to demonstrate Nested Gage R&R Study.
